[PMID: 38428893 PMCID: PMC10906636 DOI: 10.1097/md.0000000000037333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 02/01/2024] [Indexed: 03/03/2024] Open
Abstract
RATIONALE Ophthalmologists mainly treat epithelial ingrowth by lifting the flap and scraping the ingrowth or using scraping combined with phototherapeutic keratectomy, mitomycin C, and so on. The potential usefulness of nonsteroidal anti-inflammatory drugs in such circumstances has not been reported before. PATIENT CONCERNS A 32-year-old man and a 25-year-old man underwent lifting and scraping of the flap and phototherapeutic keratectomy to remove the epithelial ingrowths. Unfortunately, the ingrowths recurred and continued to develop. DIAGNOSIS The patients were diagnosed with corneal epithelial ingrowth. INTERVENTIONS The administration of bromfenac sodium and fluorometholone eye drops. OUTCOMES Epithelial ingrowths in both patients disappeared after 6 and 1 month of treatment, respectively. There were no adverse reactions to the eye drops. LESSONS Nonsteroidal anti-inflammatory drugs may be broadly applied in the treatment of epithelial ingrowth after laser in situ keratomileusis.

Traumatic Flap Complications After Femtosecond LASIK. Cornea 2022; 41:604-608. [PMID: 35383617 DOI: 10.1097/ico.0000000000002782] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 04/12/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE The purpose of this article was to evaluate the prognosis of traumatic flap dislocation or avulsion in a large series of laser-assisted in situ keratomileusis (LASIK) cases. METHODS Retrospective, consecutive, noncomparative case series analyzes the visual and anatomical results after flap dislocation or avulsion, caused by trauma occurred at least 1 month after LASIK. RESULTS A total of 37,315 eyes of 19,602 patients were reviewed. A traumatic flap complication was observed in 9 eyes of 9 patients, with a maximum interval of 37 months after surgery. Flap dislocation with central full-thickness folds was found in 5 cases; flap lifting and repositioning achieved a full recovery of uncorrected visual acuity. In another case, a partially detached flap was repositioned by a microsponge without lifting; self-limiting localized epithelial ingrowth followed. In 3 eyes, a complete flap avulsion occurred and, after epithelialization, a moderate refractive change was observed, comprised between -0.25 and -1 diopters (D) of spherical equivalent, with astigmatism <1 D; in 1 eye, the resulting myopia was corrected by repeat femtosecond LASIK. CONCLUSIONS Traumatic flap complications after femtosecond LASIK are rare but can occur even in the long term; they have a favorable anatomic and visual prognosis.

Abstract
Background Traumatic dislocation of laser-assisted in situ keratomileusis (LASIK) corneal flaps is an uncommon postoperative complication that could occur any time after LASIK, and could be visually devastating. We evaluated the visual outcomes, corneal sensation, tear function, and dry eye questionnaire results of patients with traumatic dislocation of LASIK flaps, including one LASIK flap amputation. Methods This is a retrospective case series. Seven patients who were diagnosed with traumatic displacement of the LASIK flap and underwent flap replacement surgery between August 2014 and January 2019 were included.Patient’s visual acuity, refraction, corneal sensitivity, non-invasive tear breakup time (NIBUT), tear meniscus height (TMH), and ocular surface disease index (OSDI) results were evaluated. Results The patients’ mean age was 35.86 ± 5.84 years, and 42.9 % (3/7) were male. The mean duration from LASIK to trauma was 8.86 ± 2.48 years.The mean preoperative and postoperative six-month corrected distance visual acuity (CDVA) were 0.55 ± 0.34 and 0.02 ± 0.03, respectively. The mean spherical equivalent and astigmatism at six months postoperatively was − 1.0 ± 0.95 D and − 0.5 ± 0.25 D, respectively. The corneal flap was clear and well-positioned at the final follow-up (mean: 28.57 ± 6.9 months). 85.71 % (6/7) of the patients showed worse corneal sensation in the injured eye. Interocular OSDI discrepancy was less in those whose last visit was more than 30 months after the trauma. Conclusions Postoperative CDVAat six months was improved, and the refractive data also showed some improvement. The corneal nerve and tear function recovery peaked before 30 months, while the OSDI continued to show a strong trend of improvement beyond 30 months.

Abstract
Traumatic flap displacement and epithelial ingrowth after microkeratome-assisted laser in situ keratomileusis (LASIK) is a widely described potentially sight-threatening complication. However, this complication is rare when a femtosecond laser is used to create the LASIK flap. We present a case of epithelial ingrowth after late traumatic femtosecond-assisted LASIK flap dislocation. A 25-year-old woman presented to our emergency department after being scratched in the right eye by her cat. The patient had bilateral myopic femtosecond-assisted LASIK surgery 5 years previously with good postoperative visual acuity. Ocular examination showed nasal dislocation of the flap. Follow-up examinations showed epithelial ingrowth. She was referred for reconstructive surgery in which the epithelial ingrowth was removed and the flap repositioned. Follow-up examinations showed an excellent result.

Abstract
RATIONALE Traumatic flap dislocation might occur anytime after laser in situ keratomileusis (LASIK), but it is rarely concomitantly complicated with epithelial ingrowth, infectious keratitis, and diffuse lamellar keratitis altogether. Here we report a case of traumatic LASIK flap inversion with epithelial ingrowth, Propionibacterium acnes infection, and diffuse lamellar keratitis. PATIENT CONCERNS A 42-year-old man receiving bilateral LASIK surgery 10 years ago complained of right eye pain for 6 days after twig injury. Temporal flap inversion with epithelial ingrowth and dense infiltration at the interface were noted. DIAGNOSES Traumatic LASIK flap inversion with epithelial ingrowth, Propionibacterium acnes infection and diffuse lamellar keratitis. INTERVENTIONS Removal of corneal epithelium around the flap inversion site, flap lifting, scraping of epithelial ingrowth, removal of the dense infiltrate, alcohol soaking, interface irrigation with antibiotics, and flap reposition were performed. Diffuse lamellar keratitis was noted postoperatively. Culture of the infiltrate revealed P acnes. The infiltrate subsided and the cornea cleared up under topical antibiotics and steroid. OUTCOMES The visual acuity returned to 20/20. No recurrent epithelial ingrowth or infiltrate was noted during the follow-up. LESSONS This is the first report of Propionibacterium acnes keratitis after traumatic flap inversion. Although epithelial ingrowth, infectious keratitis, and diffuse lamellar keratitis all developed after the flap inversion, early recognition and proper intervention lead to a good result without sequels.

Abstract
We studied the early protein profile in the ocular tissue extracted after LASIK and SMILE surgery. SMILE and LASIK was performed in contralateral eyes and stromal tissue samples were collected from 10 eyes of 5 donors. The stromal tissue samples were analyzed using label free quantification approach and ITRAQ labelling approach in LC-MS/MS. Combined functional analysis revealed many differentially expressed proteins which were involved in important biological processes. About 117 unique differentially expressed proteins were identified using two different proteomic approaches. Collagens, proteoglycans, corneal crystallins were enriched and showed differential expression in SMILE and LASIK as compared to the non-surgical control. Apart from these, 14-3-3 class of proteins, Lysozyme (LYZ), Macrophage Migratory Inhibitory Factor protein (MIF), Pigment Epithelial Derived Factor (PEDF) were differentially expressed when compared between LASIK and SMILE. Peroxiredoxin 1 (PRDX1) expression was found to be reduced in LASIK as compared to SMILE. The expression of Lysozyme C and Macrophage Migratory Inhibitory Factor inflammatory response was found to be less in SMILE as compared to LASIK. Western blot validation of specific markers such as Collagen IV (COL4), Keratocan (KERA), Lumican (LUM), Aldehyde dehydrogenase 3 A1 (ALDH3A1), Lysozyme C (LYZC) confirmed the differences in the protein levels observed in SMILE and LASIK operated tissues as compared to non-surgical controls. In conclusion, this study revealed the early molecular changes occurring in the cornea resulting from these two surgical procedures which may have implications on managing post-operative complications.

Abstract
PURPOSE To determine factors associated with early flap misalignment following microkeratome-assisted laser in situ keratomileusis. MATERIALS AND METHODS This retrospective study included the right eyes of consecutive patients who underwent laser in situ keratomileusis procedure between 2005 and 2016 at Care-Vision Laser Centers, Tel-Aviv, Israel. Patients were divided into two groups according to whether or not they subsequently developed early flap misalignment. RESULTS A total of 14,582 eyes (mean age of patients: 32.4 ± 10.3 years) were included. Post-laser in situ keratomileusis early flap misalignment developed in 158 eyes (1.1%). Misalignment was more frequent during the spring (32.3% vs 22.8%, p = 0.003) and in a higher operating room temperature (23.34 ± 1.06 vs 22.98 ± 1.26, p < 0.001). In addition, in the misalignment group, there was a higher rate with the of use of the a Moria M2 microkeratome (rather than sub-Bowman's keratomileusis microkeratome) head (55.2% vs 40.5%, respectively, p < 0.001). In a multivariable analysis adjusted for surgeon and year of surgery, high operating room temperature (odds ratio = 1.22, p = 0.006), treatment zone of 9.0 mm (as opposed to smaller treatment zones, odds ratio = 1.54, p = 0.04), and springtime (odds ratio = 1.58, p = 0.02) were associated with flap misalignment. There was a significant difference in misalignment rates between surgeons (p = 0.02). CONCLUSION This study found that larger treatment zones, higher operating room temperature, operating during the spring, and the use of Moria M2 microkeratome were associated with increased flap misalignment rates. The association with operating room temperature and seasonal variation is of interest and merits further research.

Abstract
Small incision lenticule extraction (SMILE) keratorefractive surgery technique is a laser surgery alternative to common methods that doesn't require laser ablation of the cornea. Despite its novelty, SMILE technique has already demonstrated positive clinical results comparable to Photorefractive Keratectomy (PRK) and Laser-Assisted in Situ Keratomileusis (LASIK), which led to its widespread application in clinical practice. Compared with other keratorefractive techniques, SMILE has a number of distinct advantage including high biomechanical stability of the cornea, low risk of dry eye syndrome, absence of a corneal flap and associated complications, preservation of corneal epithelium. The article describes the most common SMILE modifications, its weak points and possible complications, as well as methods of additional correction of remaining ametropy.
