| Sumario: | Study of the macular retinal thickness measured by Optical Coherence Tomography after refractive surgery with ICL phakic lens INTRODUCTION Phakic intraocular lenses (PIOLs) have been shown to be an effective surgical option for the treatment of ametropia of various refractive ranges. Several published studies have confirmed the Visian Implantable Collamer Lens (ICL; ST16R Surgical AG, Nidau, Switzerland) ICL implantation as an effective treatment to correct myopia, hyperopia or astigmatism. PURPOSE: To determine macular thickness changes after posterior chamber phakic intraocular lens implantation for the correction of ametropia using spectral domain optical coherence tomography (OCT). MATERIAL AND METHODS: Prospective study was conducted in 111 eyes of 58 patients underwent implantation of the implantable Collamer lens (ICL). Patients were evaluated before surgery and after surgery at week 4 and week 12. Visual acuity (VA), intraocular pressure, anterior chamber depth, pupil diameter and macular thickness with Spectralis coherence tomography were measured. RESULTS: 111 eyes from 58 patients have been studied. The mean age is 33,8 ± 6.3 years (26-50) . Mean preoperative spherical equivalent refraction was -7,793 ± 5,268. Mean postoperative spherical equivalent refraction 3 months after the surgery was -0.094 ± 0,788 D. The foveal macular thickness was de 287± 24 µm before de surgery and 290 y 293 µm at 1 and 3 months after the surgery without any significant difference in any of the areas. Uncorrected visual acuity improved in all cases and no changes in macular thickness and macular volume were found after the surgery. There were no cases of cystoid macular edema. CONCLUSIONS: The implantation of ICL has been shown to be an effective surgical option for the treatment of refractive errors. No cases of macular edema develops after surgery in our patients. The spectral domain optical coherence tomography was notable to detect any increase in macular thickness in this study period. |
