Correction of High Myopia by Worst-Fechner Biconcave Lens

ABSTRACT

For the purpose of correction of high myopia, we had implanted Worst-Fechner Biconcave Lens (Ophtec B.V., Groningen, Holland) in the 10 phakic eyes which were more myopic than -8.0 D. We examined postoperative visual acuity and complications. Postoperative uncorrected visual acuity was from 0.3 to 1.0. Cataract, glaucoma, chronic iridocyclitis and macular edema or retinal detachment did not occur and during the iris fluorescein angiography of 4 eyes there was no leakage of dye at the fixation site of iris by haptic of the lens. But all patients complained of glare. In the 3 eyes which were followed up for 12 months, corneal endothelial cell loss occurred continuously and the endothelial cell loss was 17.2% at the central cornea and 19.5% at the paracentral cornea. Therefore, long term follow up is necessary.
