Retropupillary Fixation of Iris Claw Lens with L-shaped Scleral Pocket Incision by Hyung-il Kim, Si Soo Lim, Beum Joon Cho, Ju Hong Park, South Korea


ABSTRACT

Introduction:

Retropupillary fixation of iris claw lens have been used in cases of aphakia or inadequate capsular support during cataract surgery. But, this method require 5.5mm scleral tunnel incision, so that is difficult to maintain anterior chamber and can induce astigmatism and hypotony. We introduce a method to minimize astigmatism and to maintain stable anterior chamber by using the L-shaped scleral pocket incision.

Method:

We made the L-shaped scleral pocket incision wound with a side length of 2.75 mm in cases such as aphakia or lens dislocation. After inserting the iris claw lens through the L-shaped scleral pocket incision, iris fixing part was fixed in the direction of 3 o’clock and 9 o’clock. Thereafter, the remaining viscoelastic material was removed and the scleral pocket was sutured using 10 nylon.

Result:

We retrospectively reviewed the medical record of patient, who got the surgery of retropupillary fixation of iris claw lens with L-shaped scleral pocket incision between January 2016 to December 2016 and observed for more than 3 months. There were 6 male and 4 females, and the average age was 74.2 ± 7.9 years old (67-84). The best corrected visual acuity have been significantly improved from 0.54 ± 0.72 before surgery to 0.37 ± 0.45 at postoperative 3 months.(P <0.05) Corneal astigmatism have not shown significant difference from 1.50 ± 1.84 before surgery to 1.30 ± 1.52 at postoperative 3 months. There were no significant complications such as endophthalmitis, macula edema, bullous keratopathy, retinal detachment.

Conclusion:

The retropupillary fixation of iris claw lens by using the L-shaped scleral pocket incision wound makes it possible to reduce astigmatism as compared with the conventional method of using a 5.5 mm scleral tunnel incision. It is thought that L-shaped scleral pocket method is a more safe and convenient than conventional method for recovering visual acuity.
