Randomized Controlled Study of Ocular Lubrication Versus Bandage Contact Lens in the Primary Treatment of Recurrent Corneal Erosion Syndrome.

PURPOSE: To investigate the efficacy of bandage contact lenses (BCLs) in comparison with that of ocular lubricants (OLs) in the initial management of recurrent corneal erosion syndrome. METHODS: A randomized controlled trial of 29 patients with recurrent corneal erosion syndrome presenting to the ophthalmology departments of the Oxford Eye Hospital and the Royal Berkshire Hospital, United Kingdom. The patients were randomized to wear either BCLs (for a 3-month duration, replaced every 30 days) or use OLs (4 times a day, with Lacri-Lube ointment at night for 3 months). The patients were assessed monthly for 4 months, and their symptoms were graded by visual analog scores. The main outcome measure was the complete resolution of symptoms with no noticeable corneal surface abnormality. Patients with a complete resolution were followed up for another 3 months to check for recurrence. RESULTS: Fourteen patients were randomized to the BCL arm, and 15 were randomized to the OL arm. After 3 months, a complete resolution was achieved in 71% of the patients (10/14) with BCLs compared with that achieved in 73% of the patients (11/15) on OLs (P > 0.05). Partial resolution was noted in 7% of the patients with BCLs versus 13% of the patients on OLs. Twenty-one percent of the patients in the BCL group and 13% of the patients in the OL group failed to respond to the treatment. Patients on BCLs had earlier resolution of symptoms, with a mean time of 5 weeks compared with 9 weeks for OLs (P = 0.02). None of the patients with BCLs developed adverse side effects. CONCLUSIONS: BCLs do not increase the likelihood of complete resolution when compared with OLs in the initial management of RCES. However, BCL treatment seems safe, and some patients experience earlier relief from symptoms.

Iris-claw intraocular lenses to correct aphakia in the absence of capsule support.

PURPOSE: To evaluate the indications, postoperative visual efficacy, and complication rate after intraocular implantation of an iris-claw aphakic intraocular lens (IOL). SETTING: Oxford Eye Hospital, Oxford, United Kingdom. DESIGN: Case series. METHODS: This chart review comprised eyes with no capsule support that had anterior iris-fixation IOL implantation for aphakia between 2001 and 2009. RESULTS: The study comprised 116 eyes (104 patients). Iris-claw IOLs were inserted during primary lens surgery in 18 eyes (15.5%), during an IOL exchange procedure for dislocated posterior chamber IOLs in 19 eyes (16.4%), and as a secondary procedure in 79 eyes (68.1%). The mean follow-up was 22.4 months (range 3 to 79 months). The final corrected distance visual acuity (CDVA) was 6/12 or better in 68.9% of all eyes and in 47 of 53 eyes (88.7%) with no preoperative comorbidity. Complications included wound leak requiring resuturing in 2.6% of eyes, postoperative intraocular pressure rise in 9.5% of eyes (glaucoma escalation 0.8%), and cystoid macular edema in 7.7% of eyes (0.8% chronic). Iris-claw IOL subluxation occurred in 6.0% of eyes from 5 days to 60 months postoperatively; all the IOLs were repositioned. Corneal decompensation occurred in 1.7% of eyes; 0.8% had retinal detachments. CONCLUSIONS: Iris-claw IOL implantation for aphakia gave a good visual outcome and can be used for a wide range of indications. Postoperative complication rates were comparable to, if not better than, those with conventional anterior chamber IOLs. Correct implantation technique is critical in avoiding postoperative IOL subluxation.
