Clinical results of implanting a silicone haptic-anchor-plate intraocular lens

Abstract

Purpose: To determine whether the silicone haptic-anchor-plate mini-loop lens retains the advantages of plate and loop lenses, eliminating the risk of vitreous dislocation. Setting: Centre Hospitalier Universitaire de Brest, Service Daviel (Ophthalmologie), Hospital Augustin Morvin, Brest, France. Methods: In a prospective study, the haptic-anchor-plate lens was implanted in the bag of 125 eyes after phacoemulsification. Postoperatively, best corrected visual acuity and induced astigmatism were measured. After fibrosis, the eyes were examined for lens position, fibrosis around the mini-loops, anterior/posterior dislocation within the bag, and decentration. Results: In all eyes, the lens was well centered and located in the posterior part of the capsular bag; the bag was fibrosed around the mini-loops. There were no cases of retinal detachment or cystoid macular edema. Neodymium:YAG capsulotomy was performed in four eyes without dislocating the lens. Corrected visual acuity was 20/40 or better. Conclusion: The silicone haptic-anchor-plate lens appeared to preserve the advantages of plate and loop lenses; i.e., stabilization of the vitreous, low rates of cystoid macular edema and posterior capsulotomy, and fixation in the capsular bag.
