Transscleral fixation of posterior chamber intraocular lenses in the absence of capsular support.

PURPOSE: To evaluate the safety and efficacy of a modified technique of transscleral fixation of posterior chamber intraocular lenses (IOLs) in the management of unilateral aphakia and in cases of IOL exchange.

SETTING

El-Maghraby Eye Hospital, Jeddah, Saudi Arabia.

METHODS

This prospective study comprised 41 eyes of 41 patients who had transscleral fixation of a posterior chamber IOL using a modified technique. Of these patients, 36 had unilateral aphakia and 5 had pseudophakia requiring lens exchange. Patient age ranged from 40 to 80 years. Follow-up was 12 months.

RESULTS

Uncorrected visual acuity improved in all patients. Best corrected visual acuity was unchanged in 87.8% of patients, improved by two to four Snellen lines in 9.8%, and decreased by one or two Snellen lines in 2.4%. Most complications were minor and managed medically; only two patients required further surgical intervention.

CONCLUSION

Our modified technique is safe and effective. We recommend evaluation of longer term results.
