Customized intraocular telescope implanted in high myopic patients with advanced maculopathy

Abstract

AbstractPurpose To evaluate the results of intraocular personalized telescope implantation to improve distance best corrected visual acuity (BCVA) in high myopic patients having cataract surgery.Methods This prospective non randomized observational study included 16 eyes of 9 consecutive patients with advanced maculopathy associate to high myopia having cataract surgery. Bilateral implantation of the intraocular telescope was performed after phacoemulsification in patients having the requisites. The telescope consists of two lenses a positive high power lens is implanted in the anterior chamber and a negative one is implanted in the posterior chamber. The lenses power, magnification and residual refraction were calculated for each eye using our own software. A complete ophthalmologic exploration and measurements of eye characteristics (keratometry, axial length…) refraction and VA were performed to the eye both before and after surgery.Results The mean preoperative BCVA was 2/43. The mean postoperative BCVA was of 2/5 or better in 35% of eyes and 2/12.5 or better in 60%. The mean VA was 2/20 and only one eye had VA less than 2/40 (also before surgery). The prediction for the mean residual refraction (spherical equivalent, SE) was of ‐1.5 diopters (0.8 standard deviation, SD) and the achieved mean refraction was of ‐0.58 diopters SE (1.8 SD).Conclusion Intraocular personalized telescope is an effective option for these low vision patients; which improves magnification and distance VA without significant adverse effects in one year follow up.
