ABU DHABI — Retropupillary posterior iris fixation of an iris-claw phakic IOL through a scleral tunnel incision proved to be a safe procedure and an effective option for aphakic eyes with no capsular or zonular support in a case series of 100 patients.
"We have followed these patients for more than 3 years and found that the IOL remained stable. Only two cases needed re-enclavation of one haptic, and none required long-term anti-inflammatory or anti-glaucomatous treatment," Sreeni Edakhlon, MD, said at the World Ophthalmology Congress here.
Pigment deposition on 12 IOLs was the most common complication.
Although this method of implantation is normally used for specific and limited indications, Dr. Edakhlon believes that it is safer than anterior chamber implantation, which entails risks for the endothelium and the angle. Scleral fixation, on the other hand, has several contraindications and is a cumbersome technique, and decentration, tilt and subluxation occur frequently.
"Posterior fixation of the iris-claw lens is minimally traumatic for the eye and has a very low intra- and postoperative risk profile. Postoperatively, inflammation is minimal. The implantation process is easy, with just a short learning curve, and re-enclavation, if ever needed, is also easy," he said.
In Dr. Edakhlon's case series, all patients achieved best corrected visual acuity equal to or better than preoperative BCVA.
