Abstract
Blood-derived preparations, including autologous or allogenic serum, umbilical cord serum/plasma, and platelet-rich plasma eye drops, contain various growth factors, cytokines, and immunoglobulins that resemble natural tears. These components play important roles in corneal cell migration, proliferation, and wound healing. Blood-derived eye drops have demonstrated clinical effectiveness across a spectrum of ocular surface conditions, encompassing dry eye disease, Sjögren's syndrome, graft-versus-host disease, and neuropathic corneal pain (NCP). Currently, management of NCP remains challenging. The emergence of blood-derived eye drops represents a promising therapeutic approach. In this review, we discuss the benefits and limitations of different blood-derived eye drops, their mechanisms of action, and treatment efficacy in patients with NCP. Several studies have demonstrated the clinical efficacy of autologous serum eye drops in relieving pain and pain-like symptoms, such as allodynia and photoallodynia. Corneal nerve parameters were also significantly improved, as evidenced by increased nerve fiber density, length, nerve reflectivity, and tortuosity, as well as a decreased occurrence of beading and neuromas after the treatment. The extent of nerve regeneration correlated with improvement in patient-reported photoallodynia. Cord plasma eye drops also show potential for symptom alleviation and corneal nerve regeneration. Future directions for clinical practice and research involve standardizing preparation protocols, establishing treatment guidelines, elucidating underlying mechanisms, conducting long-term clinical trials, and implementing cost-effective measures such as scaling up manufacturing. With ongoing advancements, blood-derived eye drops hold promise as a valuable therapeutic option for patients suffering from NCP.

Abstract
PURPOSE To report a case of bilateral marginal corneal infiltration upon treatment with trastuzumab, pertuzumab, and docetaxel via novel proposed mechanisms. CASE DESCRIPTION A patient, diagnosed with metastatic breast cancer and positive for human epidermal growth factor receptor 2 (HER2) with high Ki67, presented with bilateral severe marginal corneal infiltration upon undergoing first cycle of triple chemotherapy: trastuzumab, pertuzumab, and docetaxel. Treatment with topical corticosteroids and antibiotics was unsuccessful and was replaced by allogeneic serum eye drops (SED). The case improved significantly 10 days upon starting allogeneic SED. CONCLUSIONS We propose that trastuzumab, pertuzumab, and docetaxel suppress HER2 and Ki67 in the cornea and lacrimal gland. To the best of our knowledge, our report is the first to highlight the potential impact of this triple chemotherapy on the lacrimal gland and cornea and the first to highlight the proposed role of Ki67 suppression in damaging corneal integrity.

Abstract
Purpose: Umbilical cord blood serum (UCBS) is an effective adjunctive treatment along with conventional therapy in ocular surface disorders (OSDs). It aids in rapid ocular surface restoration thereby achieving epithelial integrity, in addition to improvement in subjective and objective parameters. The study aims to compare the efficacy of human umbilical cord blood serum and autologous serum (AS) in treatment of OSD. Methods: A prospective randomized study was conducted on 101 eyes diagnosed with OSD resulting from dry eye disease (DED; n = 40), acute chemical burn (ACB; n = 21), and ocular allergy (OA; n = 40). Randomization was done in Group I, administered with AS, and Group II with UCBS. Outcomes evaluated were visual acuity (VA), eye sensation score (ESS), ocular surface disease index (OSDI), tear break-up time (TBUT), Schirmer's value, Corneal Fluorescein Score, epithelial defect, limbal ischemia, corneal clarity (CC), and improvement in grade of severity. Statistical analysis was done using Wilcoxon signed-rank, Wilcoxon rank sum, Chi-square, and Z-test with a significance level (P ≤ 0.05). Results: In DED, Group II showed significant improvement in VA, ESS, and OSDI by the 7th day, whereas the mean Schirmer, TBUT, and corneal fluorescein staining score improved by 3 months. In ACB, Group II showed improvement in VA, reepithelialization, reduction in limbal ischemia, and CC by 3 months. In OA, Group II showed improvement in ESS by day 7. Conclusion: Human umbilical cord blood serum is more effective than AS in restoring ocular surface.

Abstract
Purpose To assess the role of selected matrix metalloproteinases in defective corneal re-epithelization in patients with recurrent corneal erosions. Subjects The study group (group 1) included patients with recurrent corneal erosions qualified for phototherapeutic keratectomy. The group 1 was divided into two subgroups regarding the etiology of recurrent corneal erosions: group 1A, Cogan's basement membrane dystrophy, and group 1B, trauma. The control group (group 2) included patients with healthy eyes qualified for Epi-Bowman Keratectomy. Methods The analyzed material was the corneal epithelium collected during phototherapeutic keratectomy or Epi-Bowman Keratectomy in the study or control group, respectively. Matrix metalloproteinases concentration was determined by an immunohistochemical method using Human Magnetic Luminex® Assay. Results The study revealed a statistically significantly higher concentration of matrix metalloproteinase-2 in group 1 compared to the control and a statistically significantly higher concentration of matrix metalloproteinase-3 in group 1 compared to the control. Conclusions The results obtained in the study can prove that matrix metalloproteinase-2 and matrix metalloproteinase-3 having the ability to dissolve anchoring fibers and the corneal epithelial basement membrane could be responsible for epithelial instability and their accumulation in the corneal epithelium may induce recurrence of erosion.

Abstract
PURPOSE To measure the effects of Autologous serum (AS), Allogeneic Serum (HS) and Umbilical Cord serum (CS) eye drops in severe dry eye disease (DES), as well as to characterize and quantify several molecules in the three sera (albumin, fibronectin; Vitamin A and E; IgG, IgA and IgM; Transforming growth factor β; Epithelial growth factor). METHODS Randomized, double-blind, single-centre, three-arm (AS, HS and CS) clinical trial. Sixty-three subjects were included with severe DES, 21 in each arm of the study. Visual acuity, Schirmer test, Breakup time (BUT), lissamine green, fluorescein staining measurements and a questionnaire were performed prior to treatment, and after one-month and three-month follow-up. RESULTS There was a significant main effect of time on visual acuities, Schirmer and BUT tests and fluorescein and lissamine green staining measurements and questionnaire scores (p = 0.015, p = 0.002, p < 0.001, p < 0.001, p = 0.031 and p < 0.001, respectively), although there was no significant interaction between time and serum type, nor between serum type and the test performed. Regarding the concentration of molecules, in our study AS contained significantly higher concentrations of IgA, IgG and fibronectin whereas HS contained significantly higher concentration of IgM, vitamins A and E, TGF and albumin. Contrary to previous reports, CS did not show higher concentration of any of the molecules analysed. CONCLUSIONS AND RELEVANCE The three sera were effective in the treatment of severe DES. CS did not contain a higher proportion of molecules compared to AS/HS. More research is needed to assess the effect of AS in patients with DES and autoimmune diseases.

Abstract
Purpose: To report a case of refractory recurrent corneal erosion that occurred after Descemet’s stripping automated endothelial keratoplasty (DSAEK) in iridocorneal endothelial syndrome.Case summary: A 62-year-old male patient with iridocorneal endothelial syndrome planned to undergo ultrathin DSAEK. At the surgery, corneal epithelial debridement was performed using a No. 15 blade to enhance the surgical field visibility. Three corneal venting incisions were made before graft insertion in the recipient eye. The corneal epithelium was healed at postoperative 1 week. However, the epithelium detached at 2 weeks postoperatively. The loosened epithelium was peeled off, and a therapeutic bandage contact lens was applied. Thereafter, the corneal epithelial detachment did not improve, despite repeated corneal epithelial debridement, prolonged therapeutic bandage contact lens wear, applications of 5% sodium chloride eyedrops and autoserum eyedrops, and intake of doxycycline, steroids, and valaciclovir. Anterior stromal puncture was performed three times, and the corneal epithelium eventually attached at postoperative 8 weeks. Although recurrent corneal erosion was not observed at postoperative 10 weeks, acute graft rejection occurred but improved with immunosuppressive treatment. The corrected visual acuity was 0.8 after cataract surgery, which was performed at 1 year after DSAEK.Conclusions: Refractory recurrent corneal erosion may occur after DSAEK surgery. In such a case, an aggressive treatment including the repeated anterior stromal puncture technique may be helpful.

Abstract
Purpose: To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea.Methods: Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment.Results: After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients.Conclusions: AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.

Abstract
BACKGROUND: Recurrent corneal erosion (RCE) is characterized by excacerbation and remission episodes, reduced patients quality of life affecting their daily and professional activities. In case of conservative therapy inefficacy surgical procedures are used (Bowmans membrane polishing with diamond drill, excimer laser phototherapeutic keratectomy, anterior stromal puncture, and amniotic membrane transplantation). All methods have their advantages and weak points, as well as a certain percent of recurrence. In this regard the use of corneal collagen cross-linking is of the interest as an alternative method of the RCE surgical treatment.
MATERIALS AND METHODS: 18 patients (20 eyes) with RCE without central corneal stroma scars, aged from 30 to 66 (average 49,5 10,6, all women), after conservative treatment failure (more than 6 months) underwent cross-linking according to the Dresden protocol with the UVX device, version 1000, by IROC INNOCROSS (Switzerland).
RESULTS: All patients were asymptomatic and had no recurrence during the observation period (from 1 to 6 years, in average 2,6 1,6). There was a slight but statistically significant BCVA improvement (from 0,93 0,09 at baseline to 0,97 0,07 after intervention).
CONCLUSIONS: Crosslinking may be an additional and effective treatment in a number of RCE cases when there is no central corneal stromal scars present. To reduce stromal keratocytes alteration during the procedure modified protocols may be used.

Abstract
Background The clinical efficacy of eye drops in the treatment of recurrent corneal erosion syndrome (RCES) is not satisfactory. Many studies have confirmed the positive effect of the bandage contact lens (BCL) in corneal diseases, but not many in patients with RCES. The purpose of this study is to investigate the efficacy of the BCL compared with deproteinized calf blood extract eye gel in the initial treatment of RCES. Methods Forty-seven patients with RCES treated in our hospital from September 2010 to September 2018 were retrospectively analyzed, including 24 cases (26 eyes) in the bandage contact lenses (BCLs) group wearing bandage contact lens and 23 cases (24 eyes) in the drug group treated with deproteinized calf blood extract eye gel. The efficacy was evaluated after 3 months of treatment, with a mean follow-up time of 21.15 ± 1.71 months in the BCL group and 20.87 ± 1.89 months in the drug group. Corneal erosion resolution, pain relief, visual acuity recovery time, recurrence and complications were observed. Results After 3 months of treatment, 22 eyes (22/26, 84.6%) in the BCLs group achieved complete resolution, compared with 14 eyes (14/24, 58.3%) in the drug group (P <0.05). The corneal healing time in the BCLs group was 4.77 ± 4.51 weeks, which was significantly shorter than that in the drug group (9.83 ± 5.93 weeks (P <0.01)). At 1 and 2 months after treatment, the visual analogue score (VAS) in the BCLs group (3.28 ± 1.15 at 1 month and 1.90 ± 0.77 at 2 months) decreased more significantly than that in the drug group (4.54 ± 0.89 at 1 month and 2.43 ± 0.93 at 2months, P =0.000 at 1 month and P=0.034 at 2 months). At 3 months after treatment, the mean BCVA in the BCL group (logMAR 0.03±0.08) improved more significantly than that in the drug group (logMAR 0.14±0.12,P=0.001). The complete recovery time of visual acuity was 5.46 ± 4.43 weeks in the BCLs group, compared with 10.33 ± 6.12 weeks in the drug group (P =0.003). During further follow-up, recurrence was observed in 2 eyes (2/22, 9.1%) of the BCLs group and 6 eyes (6/14, 42.8%) of the drug group. No patient in both groups developed adverse side effects. Conclusion Bandage contact lenses are safe and effective in the initial treatment of RCES. Compared with topical deproteinized calf blood extract eye gel, the use of BCLs can provide a higher cure rate, better pain control, faster visual recovery and lower recurrence rate.

Abstract
Recurrent corneal erosion syndrome (RCES) is a common chronic disease associated with repeated episodes of epithelial disruption and is characterized by sudden onset of sharp pain in the eye, usually at night or upon waking, as well as redness, photophobia and lacrimation. The cause of the disease is considered to be impaired adhesion of the epithelial layer to the stroma, which is a consequence of abnormal regeneration of the basement membrane of corneal epithelium. A number of biological factors, including inflammatory mediators and proteinases in high concentrations, contribute to the destruction of the formed adhesion complexes. The basis of RCES diagnosis is characteristic medical history and biomicroscopy. An area of epithelium absence can be detected under direct illumination - more often in paracentral view - mainly in the lower third of the cornea, where an area of loose and irregular epithelium with microcysts or grayish inclusions can be seen. There may also be a card-like or «fingerprint» pattern. First of all, it is necessary to differentiate RCES from infectious lesions, which require a fundamentally different treatment regimen. It is believed that the first stage of treatment should include lubricants, drugs that promote epithelialization, inhibitors of matrix metalloproteinases and lipases. The «second line» of conservative treatment can include blood derivatives. If conservative therapy is ineffective, it is advised to use phototherapeutic keratectomy (PTK) or perform diamond burr polishing of Bowman's layer. The choice of a method for treating recurrent erosion should be based on the effectiveness of drug therapy, frequency of recurrence, duration of the disease, severity of clinical symptoms, availability of specific ophthalmic equipment and experience with it.

Abstract
Background Healthy corneal epithelium acts as a barrier against damage to the deeper structures in the eye. Failure in the mechanisms of corneal epithelization can lead to persistent epithelial defects of the cornea (PEDs) and can compromise its function. Epidermal growth factor (EGF) promotes the proliferation, migration, and differentiation of epithelial cells, endothelial cells, and fibroblasts during wound healing and may be beneficial in treating patients with PEDs. We, therefore, investigated the effect of EGF ointment on patients with PEDs. Methods Fifteen patients with PEDs refractory to conventional treatment were treated twice a day with EGF ointment. Patient demographics and comorbidities were noted. The epithelial healing time was determined along with the primary outcome measures in the areas of the epithelial defects, visual acuity, visual analog scale (VAS) scores, and esthesiometer scores 1 month and 2 months after treatment. Results Five eyes of herpetic keratitis (33.3%), 3 eyes of dry eye disease (20.0%), 3 eyes of bacterial keratitis (20.0%), 2 eyes of limbal stem cell deficiency (13.3%), 1 eye of diabetic neurotrophic keratitis (6.7%), and 1 eye of filamentary keratitis (6.7%) were associated with PEDs, respectively. Two months following treatment with EGF ointment, there was a reduction in the area of the epithelial defects (5.7 ± 3.9 to 0.1 ± 0.3 mm2) as well as a significant improvement in best-corrected visual acuity (0.9 ± 0.8 to 0.6 ± 0.5 LogMAR) and VAS scores (4.5 ± 1.2 to 2.5 ± 0.7) in 12 eyes (80%). Among these cases, the mean epithelial healing time was 5.5 ± 1.8 weeks. Amniotic membrane transplantation was performed on the remaining 3 (20.0%) patients that did not respond to EGF treatment. Conclusions EGF ointment could reduce symptoms and promotes corneal epithelialization of refractory PEDs. It may, therefore, be well-tolerated and a potentially beneficial addition in the management of refractory PEDs.

Abstract
PURPOSE To describe our experience with retroauricular myoperiosteal autograft for surgical coverage of exposed orbital implants. METHODS This was a single-center, retrospective, observational cohort study, in which demographic and clinical data were compiled by reviewing the clinical records of anophthalmic patients with implant exposure treated with an autogenous retroauricular myoperiosteal graft at the Instituto de Microcirugía Ocular (IMO, Barcelona, Spain) over the period January 2007 to December 2017. Main outcome was the long-term coverage of implant after retroauricular myoperiosteal autograft; secondary outcome was the rate of post-surgical complications and management. RESULTS Over the 11-year period, 27 eyes of 27 patients with implant exposure received a retroauricular myoperiosteal autograft. Mean participant age was 47.3 ± 17.9 years (range 9-78, median 45). Primary surgery was enucleation in 8 eyes (29.6%) and evisceration in 19 (70.4%). Implant materials were porous polyethylene in 17 (63%), hydroxyapatite in 3 (11.1%), and bioceramics in 4 (14.8%). In the remaining three patients (11.1%), the implant material and size were unknown. Implant exposure was diagnosed after a mean of 98 ± 111.7 months. Mean exposure diameter was 5.9 ± 3.1 mm. Mean follow-up duration after graft surgery was 37.5 ± 39 months. In four patients (14.8%), implant re-exposure was recorded and in two of these patients a re-graft using the same technique was performed. In the last follow-up session, all patients showed good implant coverage. CONCLUSIONS Myoperiosteal graft could be a valid option for the long-term management of implant exposure irrespective of primary surgery, exposed area, and implant material.

Abstract
OBJECTIVE To evaluate and compare the symptomatology and clinical findings in hyposecretory dry eye of the treatment with platelet-rich plasma (PRP) and artificial tears of sodium hyaluronate (SH). METHODS Blind single-centre prospective comparative randomized study including 83 patients with hyposecretory dry eye and mean age of 64.0 years. Two groups were differentiated depending on the treatment applied: 44 patients treated with PRP (PRP group), and 39 patients treated with artificial tears of SH (SH group). Changes in Schimer test, tear osmolarity, corneal and conjunctival staining, tear film break-up time (TF-BUT), conjunctival hyperaemia, dry eye-related symptoms with the Ocular Surface Disease Index questionnaire, and caliciform cell density were evaluated during 30 days of treatment. RESULTS Significantly larger reduction in symptomatology (p < 0.001), visual improvement (p < 0.001), reduction in hyperaemia (p < 0.001), and corneal and conjunctival staining (p < 0.001), increment of Schirmer test outcome (p ≤ 0.005), and reduction of osmolarity were found in the PRP group in both eyes compared to SH group at 15 and 30 days of treatment. Likewise, a significantly higher increment of caliciform cell density (p < 0.001) was found in the PRP group. Strong and statistically significant correlations were found in the PRP group of the change achieved in visual acuity, hyperaemia, osmolarity, and conjunctival and corneal staining with the baseline values of these variables (p < 0.001). CONCLUSION PRP treatment in hyposecretory dry eye induces a more significant positive effect over symptomatology and different dry eye signs than SH, especially in moderate and severe cases.

Abstract
Recurrent corneal erosion syndrome (RCES) is a disorder characterised by a dysfunctional epithelial ecosystem. It often begins after trauma, or in the setting of epithelial basement membrane degeneration or dystrophy. Historically, RCES has been understood as a structural derangement of the anterior corneal architecture. More recently, studies have demonstrated the important role of neuropeptides in corneal homoeostasis. Thus, RCES may also be understood as a disorder of corneal epithelial cell biology. Management of RCES can be challenging, but newer therapies have demonstrated improved efficacy for this condition. This review examines the aetiology and pathogenesis of RCES, and provides an update on current and emerging treatment modalities for the management of this disorder.

Abstract
Purpose To comprehensively review the literature regarding recurrent corneal erosion (RCE) and to present treatment options and recommendations for management. Overview RCE usually presents with sharp, unilateral pain upon awakening, in an eye with an underlying basement membrane dystrophy, prior ocular trauma, stromal dystrophy or degeneration, or prior surgery for refractive errors, cataracts, or corneal transplantation. Making the correct diagnosis requires a careful slit-lamp examination of both eyes coupled with a high degree of suspicion. Several treatments are commonly used for RCE but new therapies have been introduced recently. Conservative treatment consists of antibiotic and preservative-free lubricating drops, with topical cycloplegics and oral analgesics to control pain. Patients who are unresponsive to these therapies may benefit from therapeutic bandage contact lenses (BCL). Newer therapies include oral matrix metalloproteinase (MMP) inhibitors, blood-derived eye drops, amniotic membrane graft application, and judicious application of topical corticosteroids. Once the epithelium is healed, a course of hypertonic saline solution and/or ointment can be used. Surgical procedures may be performed in patients who fail conservative therapy. Punctal occlusion with plugs increases the tear film volume. Epithelial debridement with diamond burr polishing (DBP), anterior stromal puncture (ASP), or alcohol delamination should be considered in selected patients. DBP can be used for patients with basement membrane dystrophies and is the preferred treatment overall due to a low recurrence rate. ASP can be used for erosions outside the central visual axis. Excimer laser phototherapeutic keratectomy is an attractive option in eyes with central RCE since it precisely removes tissue while preserving corneal transparency. In patients with RCE who are also candidates for refractive surgery, photorefractive keratectomy can be considered. Summary Newly introduced therapies for RCE enable therapy to be individualized and lower the recurrence rate.

Abstract
AIM To evaluate the outcomes of alcohol delamination (ALD) of the corneal epithelium for the treatment of recurrent corneal erosion syndrome (RCES) and to implement a standardized treatment protocol for this condition utilizing evidence based practice and the findings of an internal audit. METHODS A retrospective analysis of 42 eyes of 40 patients diagnosed with RCES who were treated with ALD between January 2006 and March 2016 was conducted. Patients had 20% alcohol applied to the cornea with the use of a well for 40s. Patients were reviewed one week later in the Outpatient Department. Outcome criteria were established based on standards from other studies in the medical literature. These included, a treatment success rate of at least 72% (defined as complete resolution of symptoms one month after treatment), a postoperative complication a rate of <5% (mainly infective keratitis, and subepithelial haze), and the absence of any detrimental effect on visual acuity in ≥95% of patients. RESULTS The mean age at the time of ALD was 41.17±13.44y. Patients were followed for an average of 12.8±15.65mo. The majority were female (52.5%, n=21) and the majority of eyes treated with ALD were left eyes (62.9%, n=26). Trauma was the primary aetiology in our study population. Treatment was successful in 73.8% (n=31) of eyes and in 75% (n=30) of patients. Recurrence occurred in 26.2% of eyes at a mean of 10.41±12.63mo post treatment. CONCLUSION ALD is an efficacious and cost-effective primary surgical intervention for RCES.

Abstract
BACKGROUND Recurrent corneal erosion is a common cause of disabling ocular symptoms and predisposes the cornea to infection. It may follow corneal trauma. Measures to prevent the development of recurrent corneal erosion following corneal trauma have not been firmly established. Once recurrent corneal erosion develops, simple medical therapy (standard treatment) may lead to resolution of the episode. However, some people continue to suffer when such therapy fails and repeated episodes of erosion develop. A number of treatment and prophylactic options are then available but there is no agreement as to the best option. This review version is an update to the original version published in 2007 and a previous update published in 2012. OBJECTIVES To assess the effectiveness and adverse effects of regimens for the prophylaxis of further recurrent corneal erosion episodes, the treatment of recurrent corneal erosion and prophylaxis of the development of recurrent corneal erosion following trauma. SEARCH METHODS We searched CENTRAL, which contains the Cochrane Eyes and Vision Trials Register; MEDLINE; Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 14 December 2017. SELECTION CRITERIA We included randomised and quasi-randomised trials that compared a prophylactic or treatment regimen with another prophylaxis/treatment or no prophylaxis/treatment for people with recurrent corneal erosion. DATA COLLECTION AND ANALYSIS We used standard methods expected by Cochrane. Two authors independently screened search results, extracted data and assessed risk of bias in the included studies using the Cochrane tool for assessing risk of bias. We considered the following outcome measures: resolution of symptoms after treatment; recurrence after complete or partial resolution; symptoms (pain); adverse effects (corneal haze, astigmatism). We graded the certainty of the evidence using GRADE for the three most clinically relevant comparisons. MAIN RESULTS We included eight randomised and two quasi-randomised controlled trials in the review, encompassing 505 participants. Seven studies were from Europe (Germany, Sweden and the UK), two from East Asia (Hong Kong and Japan) and one from Australia. Nine of the studies examined treatments for episodes of recurrent corneal erosions and one study considered prophylaxis to prevent development of recurrent corneal erosions after injury. Two of the nine treatment studies also enrolled participants in a study of prophylaxis to prevent further episodes of recurrent corneal erosions. The studies were poorly reported; we judged only one study low risk of bias on all domains.Two studies compared therapeutic contact lens with topical lubrication but one of these studies was published over 30 years ago and used a therapeutic contact lens that is no longer in common use. The more recent study was a two-centre UK study with 29 participants. It provided low-certainty evidence on resolution of symptoms after treatment with similar number of participants in both groups experiencing resolution of symptoms at four months (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.62 to 1.53). There was very low-certainty evidence on recurrence after partial or total resolution at seven months' follow-up (RR 1.07, 95% CI 0.07 to 15.54). There was no evidence of an important difference in pain score (score of 3 in the contact lens group and score of 2 in the topical lubrication group, low-certainty evidence) and no adverse effects were reported. The older study, using a contact lens no longer in common use, found an increased risk of pain and complications with the contact lens compared with hypromellose drops and paraffin ointment at night.A single-centre, Australian study, with 33 participants, provided low-certainty evidence of an increased risk of recurrence with phototherapeutic keratectomy compared with alcohol delamination but with wide confidence intervals, compatible with increased or decreased risk (RR 1.27, 95% CI 0.48 to 3.37). Time to recurrence was similar in both groups (6.5 and 6 months, low-certainty evidence). On average people receiving phototherapeutic keratectomy reported less pain but confidence intervals included no difference or greater pain (mean difference (MD) -0.70, 95% CI -2.23 to 0.83, low-certainty evidence). No adverse effects were reported.A 48-participant study in Hong Kong found recurrences were less common in people given diamond burr superficial keratectomy after epithelial debridement compared with sham diamond burr treatment after epithelial debridement (RR 0.07, 95% CI 0.01 to 0.50, moderate-certainty evidence). The study did not report pain scores but adverse effects such as corneal haze (RR 0.92, 95% CI 0.06 to 13.87, low-certainty evidence) and astigmatism (0.88 versus 0.44 dioptres, moderate-certainty evidence) were similar between the groups.A study comparing transepithelial versus subepithelial excimer laser ablation in 100 people found low-certainty evidence of a small increased risk of recurrence of corneal erosion at one-year follow-up in people given the transepithelial compared with subepithelial technique, however, the confidence intervals were wide and compatible with increased or decreased risk (RR 1.20, 95% CI 0.58 to 2.48, low-certainty evidence). Other outcomes were not reported.Other treatment comparisons included in this review were only addressed by studies published two decades or more ago. The results of these studies were inconclusive: excimer laser ablation (after epithelial debridement) versus no excimer laser ablation (after epithelial debridement), epithelial debridement versus anterior stromal puncture, anterior stromal puncture versus therapeutic contact lens, oral oxytetracycline and topical prednisolone (in addition to 'standard therapy') versus oral oxytetracycline (in addition to 'standard therapy') versus 'standard therapy'. AUTHORS' CONCLUSIONS Well-designed, masked, randomised controlled trials using standardised methods are needed to establish the benefits of new and existing prophylactic and treatment regimes for recurrent corneal erosion. Studies included in this review have been of insufficient size and quality to provide firm evidence to inform the development of management guidelines. International consensus is also needed to progress research efforts towards evaluation of the major effective treatments for recurrent corneal erosions.

Abstract
PURPOSE To evaluate the role of umbilical cord serum (UCS) and autologous serum (AS) therapy in reepithelialization of corneal graft after keratoplasty in a randomized controlled trial. METHODS A total of 105 eyes with epithelial defect (ED) after keratoplasty (penetrating keratoplasty-67 and anterior lamellar keratoplasty-38) on the first postoperative day were included in the study. The eyes were randomized into three groups: UCS (n=35), AS (n=35), and artificial tears (AT) (n=35). All patients received standard postoperative medical therapy. The primary outcome measure was time to epithelialization, and secondary outcome measures were best-corrected visual acuity and graft clarity. RESULTS The ED healed completely in 103 eyes. The mean time for complete reepithelialization was 2.5±2.1, 3.1±2.2, and 4.5±1.4 days in UCS, AS, and AT groups, respectively. The mean percentage decrease in the size of the ED was significantly better in the UCS and AS groups as compared with the AT group (P=0.001). The rate of reepithelialization was comparable between the AS and UCS groups (P=0.3). On bivariate analysis, significant correlation was found between the mean size of postoperative ED, grade of the donor cornea (P=0.001), and the presence of preoperative ED (P=0.001). No complications were associated with the use of serum therapy. CONCLUSION Most of the cases of postkeratoplasty corneal ED can be managed with AT only. The serum therapy (AS/UCS) helps in the faster reepithelialization of postkeratoplasty ED as compared with AT and may be considered as a treatment option for early epithelial healing.

Abstract
Ocular chemical burns are an ophthalmic emergency and are responsible for 11.5%-22.1% of ocular injuries. Immediate copious irrigation is universally recommended in acute ocular burns to remove the offending agent and minimize damage. Conventional medical therapy consists of the use of agents that promote epithelialization, minimize inflammation, and prevent cicatricial complications. Biological fluids such as autologous serum, umbilical cord blood serum, platelet-rich plasma, and amniotic membrane suspension are a rich source of growth factors and promote healing when used as adjuncts to conventional therapy. Surgical treatment of acute ocular burns includes the debridement of the necrotic tissue, application of tissue adhesives, tenoplasty, and tectonic keratoplasty. Amniotic membrane transplantation is a novel surgical treatment that is increasingly being used as an adjunct to conventional treatment to promote epithelial healing, minimize pain, and restore visual acuity. Various experimental treatments that aim to promote wound healing and minimize inflammation are being evaluated such as human mesenchymal and adipose stem cells, beta-1,3 glucan, angiotensin-converting enzyme inhibitors, cultivated fibroblasts, zinc desferrioxamine, antifibrinolytic agents, antioxidants, collagen cross-linking, and inhibitors of corneal neovascularization.

Abstract
PurposeDry eye syndrome (DES) causes significant morbidity. Trials of blood-derived products in treatment of the condition show promising results. However, their production is expensive and time-consuming. We investigate fingerprick autologous blood (FAB) as an alternative low-cost, readily accessible treatment for DES.Patients and methodsProspective, non-comparative, interventional case series. In total, 29 eyes of 16 DES patients (2 males and 14 females) from two NHS sites in the United Kingdom. Patients instructed to clean a finger, prick with a blood lancet, and apply a drop of blood to the lower fornix of the affected eye(s), 4 times daily for 8 weeks then stop and review 4 weeks later. Follow-up visits occurred ~3 days, 2, 4, 8 weeks into therapy, and 4 weeks post-cessation. At each visit, visual acuity, corneal staining, Schirmer's test, tear break-up time (TBUT), and ocular comfort index (OCI) were measured, and photographs taken. Results were analysed using Student's paired t-test.ResultsAt 8 weeks, there was improvement in mean Oxford corneal staining grade (3.31 to 2.07 (P<0.0001)), TBUT (5.00 to 7.80 s (P<0.05)), visual acuity (0.08 to 0.01 LogMAR equivalent (P<0.05)), and OCI score (56.03 to 39.72 (P<0.0001)). There was no statistically significant change in Schirmer's test results. Four weeks post-cessation versus immediately after completion of FAB therapy, mean staining grade worsened from 2.07 to 2.86 (P<0.0001). OCI score worsened from 39.72 to 44.67 (P<0.05).ConclusionsIn our limited case series FAB appears to be a safe and effective treatment for DES.

Abstract
PURPOSE To investigate dry eye development in the patients receiving systemic retinoic acid therapy and to compare effectiveness of Autologous Serum (AS) and preservative free artificial tear (PFAT) in the patients with dry eye disease. METHOD This prospective, crossover, double blind study was conducted on patients who have dry eyes due to systemic isotretinoin treatment for different indications. Patients detected as having dry eye during systemic isotretinoin treatment were included to our study. At baseline, 1 and 2 month of study, detailed ocular examination, best corrected visual acuity measurement, intraocular pressure measurement, and Tear Break-up Time (TBUT) and Schirmer Test (ST) without topical anesthesia were performed. We compared the efficacy of AS and PFAT. To accomplish crossover after the first month, treatment given to each patient was switched to the other treatment. Statistical analysis was measured using SPSS version 20.0. p values of < 0.05 were considered as statistically significant. RESULT At the end of the first month, there was a significant improvement for the TBUT test in both AS and PFAT groups compared to baseline (respectively p < 0.001, p < 0.001). TBUT was found to be significantly higher in the AS group compared to the PFAT group at the end of the first month (p < 0.001). At the end of the second month, TBUT was found to be significantly higher in the AS group compared to the PFAT group at the posttreatment time (p < 0.001). There was a significant OSDI score decreasing in both groups compared to that reported previously at the end of the first and second months (respectively p < 0.001, p < 0.001). OSDI score decreasing was more significant in the AS group compared to the PFAT group at both time points (respectively p < 0.001, p < 0.001). CONCLUSION AS may be an effective alternative to PFAT in the treatment of dry eye developed during isotretinoin use.

Abstract
PURPOSE To assess the effects of autologous serum eye drops on conjunctival expression of the mucin gene MUC5AC by means of quantitative reverse transcription polymerase chain reaction (RT-qPCR). METHODS A prospective and comparative interventional case series study of 38 eyes of 19 patients with different ocular surface disorders was performed before and 6 weeks after the treatment with autologous serum eye drops. All patients underwent a complete ophthalmic assessment, including evaluation of the tear film, ocular surface exploration, conjunctival impression cytology (IC), and MUC5AC detection by reverse transcription polymerase chain reaction. RESULTS A total of 34 eyes were studied by IC and MUC5AC quantitative reverse transcription polymerase chain reaction before and after treatment with autologous serum. This treatment improved breakup time, conjunctival squamous metaplasia, goblet cell density, and subjective perception in 76.2%, 70.6%, 55.9% and 73.5% of eyes, respectively. Treatment with autologous serum enhanced conjunctival expression of MUC5AC (P = 0.001), although these differences were not statistically significant if data are analyzed patient by patient (P = 0.09). In 13 of 34 eyes (38.2%), we found increased expression of MUC5AC; in 12 eyes (35.3%), no significant changes were found; and in 9 eyes (26.5%), a decreased expression was found. The MUC5AC gene upregulation was related to the conjunctival involvement before treatment and with the improvement in the degree of squamous metaplasia and the increase in the number of goblet cells in IC after treatment (P = 0.001). CONCLUSIONS Treatment with autologous serum enhances the conjunctival expression of MUC5AC by increasing the density of goblet cells, mainly in patients with severe conjunctival involvement.

Abstract
PURPOSE To evaluate the treatment of autologous serum eye drops (ASED) on dry eyes in patients with graft-versus-host disease (GVHD). METHODS A retrospective chart review of 35 patients with a history of ocular GVHD following hematopoietic stem cell transplantation that used ASED to alleviate dry eye symptoms was performed. Patients were categorized into three different groups. If patients had available ophthalmic data before and after starting treatment was group 1 (n = 14), had available ophthalmic data after starting treatment in group 2 (n = 10) and had available ophthalmic data before treatment or did not have any data after starting treatment in group 3 (n = 11). Data were collected on patient's age, gender, primary diagnosis, visual acuity and fluorescein corneal staining were collected on individual eyes in order to evaluate the efficacy of the ASED on alleviating dry eye-related signs and symptoms. RESULTS No adverse ocular effect from the ASED was found in our series (except one fungal keratitis). All patients reported either improvement (55%) or stability (45%) in their ocular symptoms upon the use of ASED. In patients with available data before and after starting treatment, the corneal staining score improved by a median of 1 (p = 0.003) and the LogMAR visual acuity had a non-significant improvement. CONCLUSION In our study, ASED used by patients with ocular GVHD were both safe and effective. ASED should be considered in patients with GVHD who suffer from dry eyes.

Abstract
PURPOSE To evaluate the effect of platelet-rich plasma (PRP) eye drops in the treatment of recurrent corneal erosions (RCE). METHODS A total of 47 eyes were included in this retrospective study. Clinical records of 20 consecutive patients with RCE who had been treated with conventional lubricant eye drops (conventional treatment group) from June 2006 to December 2008 and 27 consecutive patients treated with autologous PRP eye drops in addition to lubricant eye drops (PRP eye drops treated group) from January 2009 to September 2014 were reviewed. Major and minor recurrences were recorded and compared between two groups. RESULTS This study included 31 men and 16 women. The mean age was 44.5 ± 14.5 years (range, 19 to 86 years), and the mean follow-up duration was 14.9 ± 14.4 months (range, 6 to 64 months). Of the 27 cases in the PRP eye drops treated group, there were seven major recurrences in six eyes (22.2%) and ten minor recurrences in seven eyes (25.9%). In contrast, 16 eyes (80.0%) from the 20 patients in the conventional lubricant eye drops treated group had major recurrences, and all patients in this group reported minor recurrences. The mean frequency of recurrence was 0.06 ± 0.08 per month in the PRP eye drops treated group and 0.39 ± 0.24 per month in the conventional treatment group (p = 0.003). No side effects were noted in any of the patients over the follow-up period. CONCLUSIONS The use of PRP eye drops for the treatment of RCE was shown to be effective in reducing the recurrence rate without any significant complications.

Abstract
PURPOSE To investigate the cytokine composition and anti-inflammatory effects of allogeneic serum preparations for improved use as serum eye drops. METHODS Serum of 15 healthy blood donors was extensively screened for cytokines, including IL-1β, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12p70, IL-13, IL-15, 1L-17A, E and F, IL-21, IL-22, IL-23, IL-27, IL-28A, IL-31, IL-33, granulocyte macrophage colony-stimulating factor (GM-CSF), chemokine ligand 20 (CCL20), tumour necrosis factor (TNF)-α and TNF-β, interferon (IFN)-γ and transforming growth factor (TGF)-β. The levels of cytokines were assessed before and after heat-induced inactivation. Individual serum preparations were tested for their anti-inflammatory effect using an in vitro test to differentiate effector T lymphocytes into anti-inflammatory regulatory T cells. RESULTS The anti-inflammatory cytokine TGF-β was readily detected in the serum of all blood donors and was only modestly affected by heat-induced inactivation. Serum containing high amounts of TGF-β was more effective at inducing anti-inflammatory regulatory T cells. The serum of one healthy blood donor displayed high levels of inflammatory cytokines. CONCLUSION We propose that serum used as eye drops is screened for its cytokine content, making it possible to correlate the composition to the clinical outcome. Based on the findings in this study, tailored serum eye drops produced from allogeneic donors may provide increased anti-inflammatory effects. This may be superior to autologous serum eye drops, which in many cases are retrieved from patients with inflammatory diseases.

Abstract
There is a wide spectrum of blood-derived products that have been used in many different medical and surgical specialties with success. Blood-derived products for clinical use can be extracted from autologous or allogeneic specimens of blood, but recombinant products are also commonly used. A number of blood derivatives have been used for a wide range of ocular conditions, from the ocular surface to the retina. With stringent preparation guidelines, the potential risk of transmission of blood-borne diseases is minimized. We review blood-derived products and how they are improving the management of ocular disease.

Abstract
Among blood preparations, serum has been topically used in the management of various ocular diseases in ophthalmology. Like peripheral blood serum, umbilical cord blood serum contains a high concentration of essential tear components, growth factors, neurotrophic factors, vitamin A, fibronectin, prealbumin, and oil. Umbilical cord serum can provide basic nutrients for epithelial renewal and can facilitate the proliferation, migration, and differentiation of the ocular surface epithelium. Eye drops made from umbilical cord serum have been applied to treat various ocular surface diseases, including severe dry eye with or without Sjögren's syndrome, ocular complications in graft-versus-host disease, persistent epithelial defects, neurotrophic keratopathy, recurrent corneal erosions, ocular chemical burn, and surface problems after corneal refractive surgery. Because mesenchymal stem cells from umbilical cord blood can be used to regenerate corneal tissue and retinal nerve cells, umbilical cord serum might be applied for tissue engineering and regenerative medicine in the future.

Abstract
AIM To evaluate the role of umbilical cord blood serum (CBS) therapy in cases with persistent corneal epithelial defects (PED). METHODS Sixteen eyes of 14 patients with PED who were resistant to conventional treatment were treated with 20% umbilical cord serum eye drops. Patients were followed-up weekly until epithelization was complete. The collected data included the grade of corneal lesion (Grade I: epithelial defect+superficial vascularization, Grade II: epithelial defect+stromal edema, Grade III: corneal ulcer+stromal melting), the size of epithelial defect (pretreatment, 7(th), 14(th) and 21(st) days of treatment), and follow-up time was evaluated retrospectively. RESULTS The mean size of epithelial defect on two perpendicular axes was 5.2×4.6-mm(2) (range: 2.5-8×2.2-9 mm(2)). Mean duration of treatment was 8.3±5wk. CBS therapy was effective in 12 eyes (75%) and ineffective in 4 eyes (25%). The epithelial defects in 4 ineffective eyes were healed with amniotic membrane transplantation and tarsorrhaphy. The rate of complete healing was 12.5% by 7d, 25% by 14d, and 75% by 21d. The healing time was prolonged in Grade III eyes in comparison to eyes in Grade I or Grade II. CONCLUSION The results of the current study indicated the safety effectiveness of CBS drops in the management of PED. The grade of disease seems have a role on the healing time.

Abstract
PURPOSE This study evaluated the efficacy of 50% autologous serum eye drops in ocular surface diseases not improved by conventional therapy. METHODS We analyzed two groups: (1) acute eye pathologies (e.g., chemical burns) and (2) chronic eye pathologies (e.g., recurrent corneal erosion, neurotropic keratitis, and keratoconjunctivitis sicca). The patients were treated for surface instability after conventional therapy. The patients received therapy 5 times a day until stabilization of the framework; they then reduced therapy to 3 times a day for at least 3 months. We analyzed the best corrected visual acuity, epithelial defects, inflammation, corneal opacity, and corneal neovascularization. We also analyzed symptoms such as tearing, burning, sense of foreign body or sand, photophobia, blurred vision, and difficulty opening the eyelids. RESULTS We enrolled 15 eyes in group 1 and 11 eyes in group 2. The average therapy period was 16 ± 5.86 weeks in group 1 and 30.54 ± 20.33 weeks in group 2. The epithelial defects all resolved. Signs and symptoms improved in both groups. In group 2, the defect recurred after the suspension of therapy in 2 (18%) patients; in group 1, no defects recurred. CONCLUSIONS Autologous serum eye drops effectively stabilize and improve signs and symptoms in eyes previously treated with conventional therapy.

Abstract
BACKGROUND Autologous serum eye drops (ASEDs) have been used to treat many eye diseases. However, there are no standardized guidelines for the production and quality control (QC) of ASEDs in Korea. Our aim was to propose standardized guidelines for the production and QC of ASEDs. STUDY DESIGN AND METHODS We conducted a nationwide survey consisting of questions regarding the methods used in each hospital for the production and QC of ASEDs. The survey was sent by e-mail to 89 doctors responsible for the blood banks at different hospitals. RESULTS Thirty-two hospitals replied, and 13 hospitals reported using the ASEDs in the treatment of patients with eye diseases. The screening test for patients, amount of blood sampling, type of bottle used for blood collection, details about the production of the eye drops, and storage methods and shelf life of unopened and opened bottles of eye drops varied between hospitals. CONCLUSION Based on an analysis of the survey results and a review of the standard operating procedures and protocols for ASEDs used in Japan, Germany, England and Wales, and the United States, we proposed standardized guidelines for the production and QC of ASEDs in Korea. ASEDs are not cell therapy products in the strictest sense. However, because eye drops are composed of serum isolated from blood and are used in patients, we consider ASEDs to be the basis for cell therapy products. Therefore, ASEDs should be produced and stored according to standardized guidelines based on the Good Manufacturing Practice guidelines.

Abstract
PURPOSE To evaluate the clinical features and outcomes of patients with recurrent corneal erosion syndrome who underwent anterior stromal puncture. STUDY DESIGN Retrospective, nonrandomized, consecutive case series. METHODS Database search of patients from 2003-2013 who underwent anterior stromal puncture was conducted at a tertiary care hospital cornea clinic. Charts of 30 patients (35 eyes) were reviewed. Outcome measures included demographics, laterality, history of corneal trauma, prior ocular history, frequency and duration of symptoms, failed treatments, signs on examination, degree of symptom resolution, additional treatments needed, and complications. RESULTS Mean patient age at presentation was 37 (± 11.5 SD) years, 60% were male. A total of 83.3% of patients had unilateral and 16.7% had bilateral involvement. In all, 62.9% of eyes had prior history of corneal trauma and 2.9% had prior laser-assisted in situ keratomileusis. Ninety-seven percent of eyes had symptoms of pain upon awakening refractory to conservative treatment. In 97% of eyes, there were findings of microcysts, fingerprint lines, loose epithelium, and/or faint scars. Mean follow-up was 14 months (range: 3-120 months). At final follow-up, 62.9% of eyes were symptom free and 37.1% experienced milder episodes. Seventeen percent required additional treatment: 16.6% superficial keratectomy, 66% repeat anterior stromal puncture, and 16.7% phototherapeutic keratectomy. No complications were observed. CONCLUSION Anterior stromal puncture using a short (5/8 inch) 25 gauge bent needle is a simple, safe, and cost-effective procedure for symptomatic relief in patients with recurrent corneal erosion syndrome refractive to conservative measures. Repeat treatment may be performed prior to additional surgical intervention.

Abstract
Neurotrophic keratitis (NK) is a rare degenerative corneal disease that occurs as a result of partial or total impairment of trigeminal innervations, leading to a reduction (hypoesthesia) in or loss (anaesthesia) of corneal sensitivity. The impairment of sensory innervation causes a reduction in the lacrimation reflex and the vitality, metabolism and mitosis of epithelial cells, with subsequent deficiency in epithelial repair, stromal and intracellular oedema, loss of microvilli, and abnormal development of the basal lamina. Several recent studies have proposed different therapies based on different aetiopathogenetic theories. The aim of the therapy is to treat aetiopathogenesis and, at the same time, promote corneal healing. In this paper, we report the aetiology, diagnosis, management, and medical and surgical treatment of NK, also indicating future treatments based on the most recent studies.

Abstract
AIM To assess the impact of autologous serum (AS) eye drops on the ocular surface of patients with bilateral severe dry eye and to draw a comparison between the clinical and laboratory examinations and the degree of subjective symptoms before and after serum treatment. MATERIALS AND METHODS A three-month prospective study was conducted on 17 patients with severe dry eye. AS eye drops were applied a maximum of 12 times a day together with regular therapy. Dry eye status was evaluated by clinical examination (visual acuity, Schirmer test, tear film breakup time, vital staining, tear film debris and meniscus), conjunctival impression cytology (epithelial and goblet cell density, snake-like chromatin, HLA-DR-positive and apoptotic cells) and subjectively by the patients. RESULTS The application of AS eye drops led to a significant improvement in the Schirmer test (p < 0.01) and tear film debris (p < 0.05). The densities of goblet (p < 0.0001) and epithelial cells (p < 0.05) were significantly increased, indicating a decrease of squamous metaplasia after AS treatment. A significant decrease (p < 0.05) was found in the number of apoptotic, HLA-DR-positive and snake-like chromatin cells on the ocular surface. A significant improvement was found in all evaluated subjective symptoms. Altogether, the clinical results were improved in 77%, the laboratory results in 75% and the subjective feelings in 63% of the eyes. CONCLUSIONS We found that three-month AS treatment led especially to the improvement of ocular surface dryness and damage of the epithelium. The improvement of dry eye after AS treatment correlated well with the clinical, laboratory and subjective findings. From the patients' subjective point of view, the positive effect of AS decreased with time, but still persisted up to three months after the end of therapy.

Abstract
Corneal debridement techniques have seen evolution in instrumentation and indication. Although the techniques themselves are simple and usually effective, there is often the need for adjuvant topical therapies to augment healing and/or prevent recurrence of disease. To better understand the requirement for adjuvant therapies, the current theories of corneal wound healing are reviewed.

Abstract
PURPOSE To investigate the efficacy of umbilical cord serum eyedrops after laser epithelial keratomileusis (LASEK). METHODS Sixty patients (120 eyes) with myopia who underwent LASEK were studied. Thirty-two patients (64 eyes) were treated with 20% umbilical cord serum eyedrops in combination with conventional treatment (group A), and 28 patients (56 eyes) received conventional treatment only (group B). Epithelial healing time was analysed. Visual acuity, refraction, haze score (0-4) and tear film and ocular surface parameters were evaluated at 1, 2, 4 and 12 weeks after LASEK. The concentration of transforming growth factor (TGF)-β1 in tears was measured with ELISA at 1 week after LASEK. RESULTS No significant differences in visual acuity and refraction were found between groups. The mean time to epithelial healing was 3.53 ± 1.19 days in group A and 3.91 ± 1.41 days in group B (p = 0.18). The mean haze scores at 2 and 4 weeks were 0.59 ± 0.80 and 0.31 ± 0.54 in group A and 1.06 ± 0.91 (p = 0.02) and 0.69 ± 0.78 (p = 0.03) in group B. Four and 12 weeks after LASEK, tear film break-up time was longer and keratoepitheliopathy score was lower in group A compared with group B. The mean concentration of TGF-β1 was lower in group A compared with group B (p = 0.01). CONCLUSION Application of 20% umbilical cord serum eyedrops in addition to conventional treatment after LASEK can reduce early postoperative corneal haze and improve tear film and ocular surface parameters.

Abstract
Recurrent corneal erosion syndrome is characterized by repeated episodes of sudden onset of pain usually upon awakening or at night because of detachment of the weakly adhered corneal epithelium. Most of the cases can be attributed to trauma or superficial corneal dystrophies. Because of the variable clinical course, the disease causes much frustration to patients and to the ophthalmologists. Treatment options range from conservative management with lubricants, bandage contact lenses, and matrix metalloproteinase inhibitors to surgical interventions such as epithelial debridement, anterior stromal puncture, alcohol delamination, and excimer laser therapy.
