Abstract

SALERA, Cristina Moreira et al. Posterior chamber phakic lens for the correction of hyperopia following radial keratotomy. Arq. Bras. Oftalmol. [online]. 2003, vol.66, n.5, pp.563-566. ISSN 1678-2925.  http://dx.doi.org/10.1590/S0004-27492003000500004.

PURPOSE: To evaluate the efficacy, predictability and safety of posterior chamber phakic intraocular lens implantation in patients with hyperopia following radial keratotomy. METHODS: Retrospective analysis of six patients (10 eyes) previously submitted to radial keratotomy, who presented consecutive hyperopia and were treated with implantation of a posterior chamber phakic intraocular lens. RESULTS: The mean preoperative spherical equivalent manifest refraction was +4.65 D (ranging from +2.50 to +6.50 D) and the mean postoperative spherical equivalent obtained with manifest refraction was +0.3375D (ranging from -0.875 to +2.25 D). Comparing the preoperative and postoperative corrected visual acuity, we observed that three eyes (30%) gained two lines of visual acuity, two (20%) gained one line, one (10%) kept the same visual acuity, three eyes (30%) lost one line of visual acuity and one eye (10%) lost two lines. CONCLUSION: The implantation of posterior chamber phakic lens in order to correct hyperopia following to radial keratotomy is a new option of treatment for this undesirable complication but a larger number of eyes and a longer follow-up are required.
