Clinical results of implantation of the Medevec mini-loop haptic anchor plate foldable lenses

To evaluate the surgical performance and postoperative outcomes of 50 consecutive implantations of the Medevec VS 2 UV(TM) mini-loop silicone plate lenses.

Ege University Hospital, Eye Department, Izmir, Turkey.

Forty-three patients of either sex, aged 49 years, or older, were included in the study. Clear corneal incision, circular curvilinear capsulorhexis, phacoemulsification and implantation of the Medevec VS 2 UV(TM) mini-loop silicone plate lenses using the injector-cartridge system was performed in all cases. The mean outcome measures were ease of implantation, intraoperative and postoperative complications, postoperative centration and visual acuity.

The mean follow-up was 10.2 months (range 8-11 months). Twenty-two lenses (44 required two or more manoeuvers). In 6 cases, the lens was implanted into a bag with torn anterior capsule and in 3 patients (6 implanted into the sulcus because of a torn posterior capsule during phacoemulsification). Best corrected visual acuity was > or =7/10 in 48 eyes (96%) and > or =10/10 in 42 eyes (84%) at 8 months. The examination of the lenses after 8 months showed no sign of haze, discoloration or tilt. Mean decentration of the lenses was 0.32 mm +/- 0.19 (SD). There were no cases of cystoid macular edema or retinal detachment. YAG capsulotomy was performed in one eye.

Medevec VS 2 UV(TM) mini-loop silicone plate lenses appeared to have some learning curve for the implantation. They provided -- even in the sulcus -- excellent centration, good visual acuity and minimal postoperative complications.
