Abstract
OBJECTIVE To investigate the effects of short-term and prolonged topical instillation of 0.1% diclofenac sodium, 0.5% ketorolac tromethamine, and 0.03% flurbiprofen sodium on corneal sensitivity (CS) in ophthalmologically normal cats. ANIMALS 12 healthy adult domestic shorthair cats. PROCEDURES In the first of 2 study phases, each cat received 0.1% diclofenac sodium, 0.5% ketorolac tromethamine, 0.03% flurbiprofen sodium, and saline (0.9% NaCl; control) solutions (1 drop [0.05 mL]/eye, q 5 min for 5 treatments) in a randomized order with a 2-day washout period between treatments. For each cat, an esthesiometer was used to measure CS before treatment initiation (baseline) and at 15, 30, 45, and 60 minutes after the last dose. There was a 2-day washout period between phases. The second phase was similar to the first, except each treatment was administered at a dosage of 1 drop/eye, twice daily for 5 days and CS was measured before treatment initiation and at 15 minutes and 24 and 48 hours after the last dose. The Friedman test was used to evaluate change in CS over time. RESULTS None of the 4 treatments had a significant effect on CS over time in either study phase. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that neither short-term nor prolonged topical instillation of 3 NSAID ophthalmic solutions had any effect on the CS of healthy cats. Given potential differences in cyclooxygenase expression between healthy and diseased eyes, further investigation of the effects of topical NSAID instillation in the eyes of cats with ocular surface inflammation is warranted.

Abstract
PURPOSE To develop a mesoporous silica drug delivery system and target drop-free care after cataract surgery with a single subconjunctival injection. SETTING Laboratory. DESIGN Experimental animal study. METHODS Ketorolac was infiltration-loaded into sol-gel mesoporous silica particles encapsulated with poly(allylamine hydrochloride) and poly(sodium 4-styrenesulfonate) using a layer-by-layer adsorption technique (SG-Ket-LBL). The formulation was subjected to an in vitro and in vivo drug release study in addition to ocular toxicology evaluation. RESULTS Thermogravimetric analysis revealed that the drug loading efficiency was 4.4% for the SG-Ket-LBL particles. The in vivo safety study demonstrated that the formulation was well tolerated after subconjunctival injection and aqueous humor pharmacokinetics showed sustained therapeutic drug release for the targeted time window of 6 to 8 weeks. CONCLUSIONS Findings indicated that sol-gel mesoporous silica could be used as a drug carrier for subconjunctival administration. The tested formulation, SG-Ket-LBL, provided therapeutic ketorolac for 6 to 8 weeks, which might be used for a single subconjunctival injection to replace nonsteroidal anti-inflammatory drug eyedrops after cataract surgery.

Abstract
Surgical intervention is the most effective treatment for decreased vision resulting from cataracts. Although the current procedures for cataract surgery are safe and effective, it is well known that several complications can develop after surgery. Postoperative cystoid macular edema (CME) is a well-known complication, and prophylactic medications such as steroids and/or nonsteroidal antiinflammatory drugs are routinely used for its prevention. Ocular surface abnormalities, such as dry eye, have also been reported to develop after cataract surgery. However, the causative mechanisms for postoperative dry eye have not been definitively determined. At present, there are no prophylactic medications that are commonly used to prevent the development of postoperative dry eye. Although nonsteroidal antiinflammatory drugs are very effective in reducing the incidence and degree of postoperative CME, it is known that they can cause adverse side effects, including ocular surface abnormalities. Thus, perioperative medications must be carefully selected to improve surgical outcomes and patient satisfaction. Here, we summarize the results of recent studies on postoperative dry eye and CME that can develop after cataract surgery. We suggest appropriate combinations of medications that can be used to minimize these postsurgical complications.

Abstract
To evaluate corneal sensitivity by using the Cochet-Bonnet® esthesiometer in normal canine eyes at different time points following instillation of three different topical non-steroidal anti-inflammatory drugs (flurbiprofen sodium 0.03%, diclofenac sodium 0.1% and ketorolac tromethamine 0.5%) and benzalkonium chloride 0.01%. Six healthy mixed breed dogs from the same litter were used in two different stages. First, one drop of flurbiprofen sodium 0.03% and diclofenac sodium 0.1% in each eye; second, one drop of ketorolac tromethamine 0.5% and benzalkonium chloride 0.01% in each eye. Baseline esthesiometry was obtained before eye drop application and every 15 minutes thereafter until a total of 105 minutes of evaluation time. A one-week interval was allowed between the two treatment phases. Statistical analysis was used to compare means according to time of evaluation and drug used. Diclofenac sodium 0.1% decreased corneal sensitivity at 75 and 90 minutes (P > 0.015) with possible interference on neuronal nociceptive activity and analgesic effect while ketorolac tromethamine 0.5% did not show any variation for esthesiometry means along the evaluation. Flurbiprofen sodium 0.03% resulted in increased esthesiometry values 30 minutes after instillation (P > 0.013), increasing corneal sensitivity and possibly producing a greater irritant corneal effect over its analgesic properties. Benzalkonium chloride 0.01% significantly increased corneal sensitivity at 15 minutes of evaluation (P > 0.001), most likely resulting from its irritating effect. Esthesiometry did not allow a definite conclusion over the analgesic effect of the NSAIDs tested; however it was effective in detecting fluctuations in corneal sensitivity.

Abstract
PURPOSE Topical nonsteroidal antiinflammatory drugs (NSAIDs) are administered topically for a variety of ophthalmologic conditions. Brand diclofenac and brand ketorolac were previously shown to have topical anesthetic effects in addition to analgesic effects. Using the same method, we measured similar anesthetic effects of the 4 currently available topical NSAIDs--generic diclofenac, generic ketorolac, brand bromfenac, and brand nepafenac. METHODS Baseline corneal sensitivity was measured on 10 healthy adult volunteers with a Cochet-Bonnet esthesiometer. One drop of the agent being studied was applied to the right eye every 5 minutes for a total of 4 drops. Corneal sensitivity was measured immediately after the last topical application and every 15 minutes for 60 minutes. After a 1-week washout period, a different agent was studied until all 4 NSAIDs were evaluated. RESULTS Corneal sensitivity profiles over time were similar for all NSAIDs. Corneal sensitivity decreased significantly from baseline immediately after topical application remaining flat from 0 to 30 minutes and then rising from 45 to 60 minutes back toward baseline in all treatment groups (P < 0.001). The maximal absolute drop in corneal sensitivity as measured by pressure thresholds was greatest for diclofenac [28.6 mm (95% confidence intervals {CI}, 19.8-37.4)], followed by ketorolac [21.1 mm (95% CI, 15.1-27.1)], bromfenac [16.9 mm (10.7-23.1)], and nepafenac [16.4 mm (95% CI, 12.7-20.1)]. Only diclofenac and nepafenac were statistically different in maximal decrease in sensitivity. CONCLUSIONS All 4 currently available NSAIDs demonstrated anesthetic effects similar to brand diclofenac and brand ketorolac.

Abstract
OBJECTIVE To quantify plasma concentrations and determine adverse ocular, renal, or hepatic effects associated with repeated topical ophthalmic application of 0.1% diclofenac to healthy cats. ANIMALS 8 healthy sexually intact male cats. PROCEDURES A randomized, placebo-controlled crossover study was conducted. A topical formulation of 0.1% diclofenac was administered 4 times/d for 7 days to 4 cats, and artificial tear (control) solution was administered to the other 4 cats. After a 12-day washout period, cats received the other treatment. Ophthalmic examinations were performed daily. Plasma samples were obtained on days 1 and 7 for pharmacokinetic analysis. A CBC, serum biochemical analysis, urinalysis, determination of urine protein-to-creatinine ratio, and determination of glomerular filtration rate were performed before the start of the study and after each 7-day treatment period. RESULTS Mild conjunctival hyperemia was the only adverse ocular effect detected. Maximal drug concentration and area under the curve were significantly higher on day 7 than on day 1. Diclofenac-treated cats had a significantly lower glomerular filtration rate than did control-treated cats after the second but not after the first treatment period, presumably associated with iatrogenic hypovolemia. CONCLUSIONS AND CLINICAL RELEVANCE Topical ophthalmic administration of 0.1% diclofenac was well tolerated in healthy cats, with only mild signs of ocular irritation. Detectable systemic concentrations of diclofenac were achieved with accumulation over 7 days. Systemic absorption of diclofenac may be associated with reduced glomerular filtration rate, particularly in volume-contracted animals. Topical ophthalmic 0.1% diclofenac should be used with caution in volume-contracted or systemically ill cats.

Abstract
PURPOSE To determine whether indomethacin 0.1% eye drops are at least as effective as ketorolac 0.5% eye drops in treating ocular inflammation following cataract surgery. METHODS Prospective, multicenter, investigator-masked, parallel-group, randomized, active-controlled clinical trial. Cataract patients were randomized in a 1:1 ratio to receive indomethacin or ketorolac administered QID for 3 weeks beginning 1 day before surgery. The primary end-point was aqueous flare measured by laser flare meter at postoperative Days 1 and 7. Secondary end-points included retinal thickness, slit lamp and funduscopic examinations and postsurgical pain ratings. Safety and tolerability were also assessed. RESULTS A total of 86 patients were included in the per protocol population (n = 43 per treatment group). Indomethacin was found non-inferior to ketorolac for comparison of aqueous flare at postoperative Days 1 and 7 (Day 1: 95% CI: -2.37, 5.50; non-inferiority upper margin, 15 ph/ms and Day 7: 95% CI: -7.83, -0.94; non-inferiority upper margin, 8 ph/ms) and statistically better than ketorolac at Day 7 (p = 0.013). There were no significant between-group differences in aqueous flare and change from baseline in retinal thickness at postoperative Days 30 and 90. Indomethacin showed a higher subjective tolerance rating than ketorolac at postoperative Days 7 and 30 (p ≤ 0.044). CONCLUSION Indomethacin 0.1% was at least as effective as ketorolac 0.5% at Day 1 and more effective than ketorolac 0.5% at Day 7 in treating ocular inflammation after uncomplicated cataract surgery. Indomethacin was better tolerated than ketorolac. There were no clinically meaningful safety concerns with either treatment.

Abstract
Background To evaluate the analgesic efficacy of bromfenac sodium ophthalmic solution 0.09% compared with ketorolac tromethamine ophthalmic solution 0.5% in laser epithelial keratomileusis (LASEK) or epithelial keratomileusis (epi-LASEK), sometimes referred to as epi-LASIK. Methods Eighty eyes (from 40 patients, 18 men and 22 women) undergoing bilateral simultaneous LASEK or epi-LASEK were randomized to receive ketorolac in one eye and bromfenac in the other. Mean age was 33.13 ± 9.34 years. One drop of bromfenac or ketorolac was instilled in each eye 15 minutes and one minute prior to surgery, and two and four hours following surgery. Patients were instructed to instill the medications on-label each day through postoperative day 4. The subjects completed pain and visual blurriness assessments from day of surgery to postoperative day 4. Uncorrected visual acuity was tested on postoperative days 1 and 6. Results For each of the five days, pain scores for bromfenac-treated eyes were significantly less than that for ketorolac-treated eyes (P < 0.01). Of the 40 patients, 32 (80%) said bromfenac provided better postoperative analgesia than ketorolac. There was no statistically significant difference in visual blurriness scores between the two groups (P > 0.1). Uncorrected visual acuity did not vary significantly between the treatment groups (P > 0.1). No serious adverse events were noted. Conclusion Bromfenac is subjectively superior to ketorolac in reducing postoperative pain following LASEK or epi-LASEK. The subjects tolerated the drugs well with no serious adverse outcomes and no difference in uncorrected visual acuity.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are increasingly employed in ophthalmology to reduce miosis and inflammation, manage scleritis, and prevent and treat cystoid macular edema associated with cataract surgery. In addition, they may decrease postoperative pain and photophobia associated with refractive surgery and may reduce the itching associated with allergic conjunctivitis. In recent years, the U.S. Food and Drug Administration has approved new topical NSAIDs, and previously approved NSAIDs have been reformulated. These additions and changes result in different pharmacokinetics and dosing intervals, which may offer therapeutic advantages. For example, therapeutic effects on diabetic retinopathy and age-related macular degeneration may now be achievable. We provide an updated review on NSAIDs and a summary of their current uses in ophthalmology with attention to potential future applications.

Abstract
Sjögren's syndrome dry eye is an inflammatory disease accompanied by an impairment of the autonomous nervous system of the ocular surface. The therapy for this condition is shifting from the mere tear replacement to a more complex approach including an anti-inflammatory treatment. Clinical trials have evidenced that the use of NSAIDs is followed by a reduction of the ocular discomfort symptoms in dry-eye patients. However, sporadic case reports of corneal melting in dry-eye subjects who underwent surgical procedures has brought attention to the possible effect that NSAIDs may have on corneal sensitivity. Therefore, the effect of NSAID treatment on corneal sensitivity in normal subjects and in patients with dry eye was studied. The results of these trials seem to demonstrate that some NSAIDs, diclofenac in particular, have the effect of reducing corneal sensitivity both in normal subjects and in patients with dry eye. Therefore, NSAIDs should be used with caution in Sjögren's syndrome patients.

Abstract
PURPOSE To report a case of corneal ulceration and perforation after PRK connected with high doses of ketorolac tromethamine (Acula). METHODS A 31-year-old man presented 5 days after PRK in the left eye with corneal ulceration and perforation requiring penetrating keratoplasty. The patient admitted to using Acular every hour, ciprofloxocin every hour, and prednisolone acetate 1% QID postoperatively. RESULTS Laboratory tests, including corneal cultures, were normal. A diagnosis of corneal ulceration secondary to incorrect use of high-dose ketorolac tromethamine was made. CONCLUSION Judicious patient counseling is recommended when using topical NSAIDs in the setting of PRK.

Abstract
PURPOSE Three cases of corneal melting caused by a new nonsteroidal anti-inflammatory drug (NSAID), bromfenac sodium, are reported. CASE REPORTS Case 1: A 58-year-old man with a history of bullous keratopathy caused by Fuchs' corneal dystrophy was treated for episcleritis with topical bromfenac sodium. After 15 days of treatment, melting (80% depth) was observed inferiorly in the paracentral cornea. Case 2: A 71-year-old man underwent uncomplicated pterygium surgery, followed by treatment with topical bromfenac sodium. After 40 days of treatment, a 60%-depth corneal melt occurred in the nasal limbus. Case 3: A 76-year-old woman had a suspected bacterial corneal ulcer that resolved with topical ofloxacin; however, after 5 days of treatment with topical bromfenac sodium, a perforation occurred in the inferonasal cornea. RESULTS In all three cases, severe corneal melting was characterized by mild hyperemia, very faint infiltration, and mild pain. Conservative treatment, including the use of a bandage soft contact lens and/or antibiotics and lubrication, led to resolution in all cases. CONCLUSIONS A new NSAID, bromfenac sodium, can lead to severe corneal melting. These findings, together with similar previous reports concerning diclofenac sodium and ketorolac, suggest that careful observation is required when using topical NSAIDs in the treatment of corneal disease.

Abstract
AIM AND PURPOSE To evaluate the effects of two NSAIDs on corneal sensitivity and ocular surface in Sjögren's syndrome (SS) patients. METHODS In all, 20 SS patients with epithelial corneal defects, were randomly divided into two groups: group 1 (10 females, age 35-63 years), treated with 0.1% indomethacin, one drop three times a day; group 2 (nine females, one male, age 38-65 years) treated with 0.1% diclofenac, at the same regimen. No systemic NSAIDs were allowed. Use of tear substitute was allowed. Corneal sensitivity, corneal staining, BUT, and ocular discomfort, were evaluated before and after 15, 30 days of treatment and 7 days after NSAID discontinuation. For statistical analysis, the Student's t-test and Mann-Whitney U test were used. RESULTS Both groups showed at day 30 a statistically significant reduction of corneal sensitivity (P<0.05), although the diclofenac-treated group showed a statistically significant lower sensitivity if compared to the indomethacin-treated group (P<0.05). Corneal fluorescein score showed a statistically significantly worst alteration in group 2, 7 days after the discontinuation of the therapy (P=0.02). The ocular discomfort score was statistically significantly reduced in both groups starting from day 15 (P<0.05). DISCUSSION The results indicate that NSAIDs can be useful in resolving symptoms of ocular discomfort in SS patients. However, they should be used with caution and under close monitoring, and the treatment should be promptly discontinued if corneal epithelial defects develop or worsen during treatment.

Abstract
Neurotrophic keratopathy is one of the most challenging conditions among the disorders of wound healing of the ocular surface. In addition to bilateral assessment of corneal sensitivity, tear status and lid function must be analyzed and treated by unpreserved artificial tears and adequate lid surgery. Further conservative treatment options include hyaluronic acid and dexpanthenol as well as autologous serum. Application of recombinant growth factors (especially NGF) represents an interesting perspective. Concerning surgical interventions, temporary or permanent occlusion of the lacrimal punctum may be accompanied by lateral tarsorrhaphy which is easy to perform, potentially reversible, and in most cases successful. Depending on the type of wound healing disorder amniotic membrane transplantation may be helpful either as basal membrane transplant (graft) or as a patch, or in combination (sandwich). A tectonic keratoplasty a chaud should typically be combined with a simultaneous amniotic membrane patch and/or a lateral tarsorrhaphy to avoid persistent epithelial defects.

Abstract
PURPOSE To investigate the sterility of non-preserved autologous serum drops in hospitalized patients with persistent corneal epithelial defects. METHODS Thirty patients with persistent corneal epithelial defects (aged between 28 and 85, mean 67+/-14 years) were treated with autologous serum drops in five different wards of a university eye hospital between October 2001 and March 2002. After centrifugation of freshly collected autologous blood, the serum was stored in sterile drop bottles at refrigerator temperature (7 degrees C) and applied undiluted every 1 or 2 h up to 7 days. Using blood, chocolate, endo, and Sabouraud agar media, we assessed the sterility of autologous serum drops on the day before application and on the 4th and 7th days. Examinations performed on the 1st and 4th days included 40 autologous serum drops each and on the 7th day 120 samples (40 serum drops, 40 bottle tops, and 40 bottle bottoms). The agar media for bacterial examination were read after 48 h of incubation time, and those for fungal examination were read after 21 days. All patients had received topical autologous serum therapy and prophylactic antibiotic drops for at least 7 days. RESULTS The time period of autologous serum treatment ranged from 7 to 28 (10+/-5) days. On the 1st and 4th days autologous serum drops were sterile. On the 7th day, 3 of 40 (7.5%) samples were contaminated with Staphylococcus epidermidis. Two of these contaminations were due to a combined serum drop and bottle top contamination (5%). A third case resulted from additional bottle bottom contamination (2.5%). None of the samples examined showed signs of fungal infection. During application of autologous serum as well as during the follow-up period no patient showed any symptoms of ocular infection. CONCLUSIONS The application of autologous serum has proven to be a practicable therapy in patients with persistent corneal epithelial defects. When the drops are applied by trained personnel, the absence of contamination can be ensured up to the 4th day. By additional application of prophylactic antibiotic drops, infections may be avoided even if refrigerated non-preserved autologous serum is used up to 7 days.

Abstract
PURPOSE To compare the effect of topical ketorolac tromethamine 0.5% solution and topical diclofenac sodium 0.1% solution on the inhibition of surgically induced miosis. SETTING Tertiary care teaching hospital in South India. METHODS Fifty-one patients were prospectively randomized to receive ketorolac 0.5% or diclofenac 0.1% at 3 intervals preoperatively. Patients with diabetes mellitus, pseudoexfoliation, or local pupil abnormalities were excluded from the study. Mydriatics comprising homatropine 1% plus phenylephrine 10% were instilled in all patients 1 hour before the peribulbar block at 5 intervals. Horizontal pupil diameters were obtained at the beginning of surgery, after capsulotomy, after intraocular lens (IOL) implantation, and at the end of surgery. RESULTS The mean horizontal pupil diameter was 7.40 mm at the start of surgery in both groups. The ketorolac group showed a consistent trend toward larger pupil diameters at subsequent surgical intervals. Changes from baseline also indicated more significant inhibition of miosis in the ketorolac group. CONCLUSIONS Topical ketorolac was a more effective inhibitor of miosis than topical diclofenac during extracapsular cataract extraction and IOL implantation. It also provided a more stable mydriatic effect throughout surgery.

Abstract
PURPOSE To determine if at clinical dosages, the topical nonsteroidal anti-inflammatory drugs diclofenac and ketorolac decrease corneal sensitivity, and if there is a difference in discomfort on instillation. METHODS In a double-masked study, 30 patients were randomized to receive two of three topical drops, Endosol, diclofenac sodium, and ketorolac tromethamine. A microaesthesiometer was used to evaluate corneal sensation. Baseline corneal sensitivity was obtained on each patient. Corneal sensory thresholds were remeasured at 7 and 15 minutes following eyedrop application. Patients also completed a questionnaire that graded the burning caused by the medications. RESULTS No significant decrease in corneal sensory thresholds was found with diclofenac or ketorolac compared with control at baseline (P = .50), 7 minutes (P = .41), or 15 minutes (P = .82). There was significantly more burning with diclofenac and ketorolac compared to control. There was a small but not statistically significant (P = .28) trend of more burning with ketorolac than diclofenac. CONCLUSION Neither diclofenac nor ketorolac were found to decrease corneal sensation compared to control. There was no significant difference in burning upon instillation reported by patients.

Abstract
This prospective double-blind study was designed to assess the analgesic efficacy of ketorolac 0.5% ophthalmic solution compared with placebo in 30 healthy children undergoing extraocular muscle recession for correction of strabismus. After paracetamol 20 mg.kg-1 preoperatively, a standard anaesthetic was given. There were no significant differences in Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) and faces pain scale (FPS) scores, requirement for supplementary analgesia or in postoperative vomiting between the two groups over the following 24 h. This study did not demonstrate improved postoperative analgesia when topical ketorolac eye drops were given in addition to paracetamol. This observed lack of efficacy may reflect difficulties in the use of CHEOPS and FPS in this age group with this pain model.

Abstract
OBJECTIVE This study assessed the efficacy of 4 nonsteroidal anti-inflammatory drugs (NSAIDs) after excimer laser photorefractive keratectomy (PRK). BACKGROUND Inadequate control of pain after PRK surgery can be a severe source of distress to patients and can interfere with their willingness to undergo a second PRK procedure. METHODS This randomized, double-masked, placebo-controlled clinical study was conducted in 125 patients. Four NSAIDs (diclofenac, flurbiprofen, ketorolac, and indomethacin) were tested against a placebo group (artificial tears). Pain levels after PRK were quantified using Present Pain Intensity (PPI) and Pain Rating Indices based on rank values (PRI[R]) scores, both of which were calculated using patient responses to a modified McGill Pain Questionnaire. The PRI(R) consisted of 4 subscales-sensory (S), affective (A), evaluative (E), and miscellaneous (M)-as well as a total score (T). RESULTS Three hours after PRK, no differences in PPI scores were found between the ketorolac, diclofenac, and indomethacin groups, whereas placebo was significantly less effective than the NSAIDs. Patients who received flurbiprofen reported PPI scores that were significantly lower (P < 0.001) than those of patients who received diclofenac and indomethacin, but PPI scores in the flurbiprofen and the ketorolac groups did not differ significantly. Twenty-four hours after surgery, patients treated with flurbiprofen, ketorolac, and diclofenac reported the lowest PPI scores compared with those treated with indomethacin and placebo (P < 0.001). Moreover, flurbiprofen-treated patients also had the lowest PRI(R)T scores (P < 0.001). When the pain rating index was examined by subclass, a significantly lower PRI(R)S score was detected in the flurbiprofen group at 24 hours (P < 0.001). The PRI(R)A score was significantly higher in the placebo and indomethacin groups compared with the other groups (P < 0.001). At the 48- and 72-hour time points, flurbiprofen-treated patients again reported significantly lower PPI and PRI(R)T scores (P < 0.001 for both) in pair-wise comparisons with the other treatment groups. The number of patients who self-administered additional oral analgesics did not differ significantly between the groups. However, the mean number of analgesic tablets used was significantly higher in the placebo group than in any NSAID group (P < 0.001). The ketorolac group had the largest number of patients complaining of itching (P < 0.043). No other subjective symptoms were significantly different across groups. Finally, all NSAIDs, except flurbiprofen, prolonged the mean reepithelialization period slightly (P < 0.001). CONCLUSIONS Flurbiprofen appeared to be the most effective NSAID for the treatment of pain, even at 24 hours after surgery when pain was at a maximum.

Abstract
PURPOSE To study the changes in the corneal epithelium and corneal sensitivity of healthy subjects after the topical administration of non-steroidal anti-inflammatory drugs (NSAIDs; diclofenac, indomethacin, flurbiprofen and ketorolac) frequently used in ocular therapy. METHODS A double-masked parallel clinical study was undertaken on 90 subjects (45 men, 45 women; Caucasian; age 21-46 years, mean +/- SD 27.1 +/- 5 years). The subjects were divided into six groups: group 1 was treated with placebo, group 2 with 0.1% diclofenac, group 3 with 0.1% indomethacin, group 4 with 0.03% flurbiprofen, group 5 with 0.5% ketorolac and group 6 with 0.4% oxybuprocaine. One eye was randomly treated with the study drug and the fellow eye was treated with placebo. The medications were instilled four times, at 5 min intervals. Assessment of the corneal epithelium was carried out by vital fluorescein stain before instillation and 5, 15, 30 and 60 min after instillation of the last drop. Subjective burning sensation was assessed by asking participants to rate burning on a scale from 0 (none) to 3 (severe). After 1 week, assessment of corneal sensitivity was carried out by the Cochet-Bonnet method, repeating the above scheme of instillation and measurement times. RESULTS None of the study drugs, with the exception of oxybuprocaine, produced evident epithelial damage. All the drugs caused a mean burning sensation greater than the placebo. The diclofenac-treated group showed a statistically significant decrease in corneal sensitivity (p < 0.001) at the measurement carried out 15 min after instillation of the last drop and lasting up to the end of the study, when the corneal anaesthesia was similar to that induced by the topical anaesthetic treatment. No significant changes were demonstrated for the other NSAIDs when compared either with the placebo-treated eyes or with the fellow eyes. CONCLUSIONS Despite a similar mechanism of action and analgesic activity to the other NSAIDs tested, diclofenac was able to induce a reduction in corneal sensitivity. More studies are needed to determine the mechanism of action responsible for this effect.

Abstract
AIMS To evaluate the analgesic effect of topical sodium diclofenac 0.1% during retinal laser photocoagulation. METHODS 87 patients, 45 with proliferative diabetic retinopathy treated with two sessions of panretinal photocoagulation (group A), and 42 patients with non-proliferative diabetic retinopathy who underwent grid treatment of the posterior pole (19 bilaterally) (group B). Sodium diclofenac 0.1% or sodium chloride 0.9% drops were topically applied 30-135 minutes before laser treatment in a masked fashion. Patients who had two sessions were given the alternate drug in the second one. Pain level was evaluated immediately after laser treatment with the visual analogue scale (VAS). The results were statistically analysed. RESULTS Patients in group A reported pain in 85/90 sessions (94%). The average pain level was 44.2% with sodium diclofenac 0.1% drops and 53.1% with sodium chloride 0.9% drops (p = 0.011 by paired t test). Patients in group B reported pain in only 16/60 sessions (26. 7%), and the pain level ranged from 10% to 60% regardless of the kind of drops used. There was no correlation in either group between level of pain and time interval from application of the drops to laser treatment (30-135 minutes) or average energy level used (100-500 mW). CONCLUSION Sodium diclofenac 0.1% is useful for pain reduction and should be applied before panretinal photocoagulation.

Abstract
PURPOSE To compare the relative effectiveness of diclofenac, flurbiprofen, ketorolac, and prednisolone acetate in relieving photophobia after pupil dilation for fundus examination. SETTING Eye, Ear, Nose, and Throat Hospital, New Orleans, Louisiana, USA. METHODS This prospective, blind, placebo-controlled study comprised 105 patients randomly assigned to 1 of 10 treatment groups. Five minutes after instillation of dilating drops, each patient received drops of different test medications in the right and left eyes. Light sensitivity and pupil measurement tests were performed over 2 hours after the pharmacological mydriasis. After photostimulation, patients were asked to rate their photosensitivity on numerical and analog scales and to indicate a filter value required to alleviate right-induced discomfort. Test results were analyzed to detect differences among the pain levels associated with each treatment. RESULTS There were no significant differences between the placebo and any active treatment drug at any time during the study. CONCLUSION These findings suggest that mediators other than prostaglandins may have a role in photosensitivity or that increased postmydriatic photosensitivity is a result of higher light levels entering the eye through the dilated pupil.

Abstract
OBJECTIVE This study aimed to compare the anti-inflammatory and analgesic effects of topical diclofenac sodium 0.1% (Voltaren) with prednisolone sodium phosphate 1% ophthalmic solution after strabismus surgery. DESIGN A prospective, double-masked, randomized, two-center clinical trial. PARTICIPANTS Eighty eyes of 52 patients undergoing strabismus surgery were examined. INTERVENTION For 1 week after surgery, the eye that was operated on received one drop of either diclofenac or prednisolone four times a day. MAIN OUTCOME MEASURES The diclofenac- and prednisolone-treated eyes were compared on postoperative days 3 and 7 with respect to signs of inflammation (e.g., erythema, edema, discharge), patient comfort, and conjunctival incisional healing. RESULTS On postoperative day 7, in eyes that received prednisolone, the conjunctival defects were larger (P = 0.004) and more frequent (P = 0.02). For all subjects, despite adequate statistical power, there was no statistically significant difference in inflammatory scores between eyes that received diclofenac or prednisolone. In cases of bilateral surgery, however, there was less postoperative erythema and edema in the diclofenac-treated eyes. CONCLUSIONS In the first week after strabismus surgery, topical diclofenac proved at least as effective as prednisolone in controlling inflammation and discomfort with less delay in incisional wound healing. Topical diclofenac, a nonsteroidal anti-inflammatory agent, may be considered for use after strabismus surgery in place of corticosteroids.

Abstract
OBJECTIVE To evaluate the effectiveness of an ophthalmic nonsteroidal anti-inflammatory drug (NSAID) in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions and no pressure patch. DESIGN A single-center, randomized, double-masked, placebo-controlled study. PARTICIPANTS One hundred patients with noninfected, non-contact lens-related, traumatic or foreign body removal-related corneal abrasions less than 36 hours in duration. INTERVENTION All patients received a cycloplegic drop and erythromycin or polymyxin B (Polysporin Ophthalmic Ointment, Burroughs Wellcome, Research Triangle Park, NC). Patients were then randomized to receive either ketorolac tromethamine 0.5% ophthalmic solution or control vehicle drops. MAIN OUTCOME MEASURES The main outcome measures were six subjective symptoms monitored daily, evaluation of corneal abrasion, and determination of adverse events. Long-term complications were determined 3 to 8 months after randomization. RESULTS Twelve patients were excluded from the study. One day after randomization, patients receiving ketorolac tromethamine 0.5% ophthalmic solution noted significantly decreased levels of pain (P < 0.002), photophobia (P < 0.009), and foreign body sensation (P < 0.003) as compared with the control vehicle group. In addition, the time to resumption of normal activities was shorter in the group who received ketorolac tromethamine 0.5% ophthalmic solution (P < 0.001). There was no statistical difference in the amount of tearing, healing time, acuity changes, or complication rates between the two groups. CONCLUSIONS Ketorolac tromethamine 0.5% ophthalmic solution provides increased patient comfort without clinical adverse effects when used as adjunctive therapy in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions.
