Three-haptic intraocular lens for myopia: early results

To report the intraoperative experience and early postoperative results of implantation of an intraocular lens (IOL) developed specifically for myopic eyes.

Wolverhampton Eye Infirmary, Wolverhampton, United Kingdom.

This retrospective study evaluated consecutive highly myopic eyes having implantation of a Bigbag IOL from November 2003 to December 2007. Before IOL placement, a 2.8 mm clear corneal incision was created and phacoemulsification performed. The IOL was implanted using the dedicated folder and injector supplied by the manufacturer.

The study evaluated 67 eyes (48 patients) with a mean follow-up of 8.5 months (range 0.75 to 31 months). Intraoperative complications were IOL haptic damage from the injector system (3 eyes; 4.5%) and posterior capsule tear (1 eye; 1.5%). Postoperative complications were posterior capsule opacification (29 eyes; 43%), retinal detachment (1 eye; 1.5%), and iritis (1 eye; 1.5%). The postoperative corrected distance visual acuity was 0.10 logMAR or better in 24 eyes (35.8%) and 0.18 to 0.48 logMAR in 32 eyes (47.8%). Forty-three eyes (64.2%) were within +/-1.00 diopter of the intended refractive outcome.

Preliminary results indicate that this 3-haptic IOL is safe and appropriate for use in highly myopic patients having cataract surgery.
