To evaluate the outcomes after implantation of an intraocular personalized telescope: magnification effect and its relationship to improvement on best corrected visual acuity (BCVA) and refractive results in high myopic patients having cataract surgery.
This retrospective study included the eyes of patients with advanced maculopathy associate to high myopia having cataract surgery. Bilateral implantation of an intraocular customized telescope was performed after phacoemulsification. 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. The complete ophthalmologic exploration and measurements of eye characteristics (keratometry, axial length…) refraction and VA before and after surgery was collected and analysed from eyes with one year follow-up
We selected 28 eyes of 14 patients. All the patients obtained a visual magnification of 1.6 or better and 64% of patients reached 2.5 or better. 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. 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).
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.
