OBSERVATIONAL STUDY
Prevalence of cataract after collagen copolymer phakic intraocular lens implantation for myopia, hyperopia, and astigmatism.
Journal of Cataract and Refractive Surgery 2015 April
PURPOSE: To evaluate the prevalence of cataract after Implantable Collamer Lens phakic intraocular lens (pIOL) implantation with different models at different ages and for different refractive powers.
SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, Spain.
DESIGN: Retrospective nonrandomized clinical study.
METHODS: The pIOL (models V4, V4b, or V4c) was implanted in all cases.
RESULTS: The study included 3420 eyes (1898 patients). The mean patient age at surgery was 31.2 years ± 6.4 (SD) (range 18 to 50 years) and the mean spherical refractive error, -7.27 ± 5.24 diopters (D) (range -26.5 to 12.5 D). Twenty-one eyes (0.61%) of 15 patients had pIOL explantation (all model V4) because cataract developed. The mean age of the patients who had explantation was 39.43 ± 4.57 years; 7 were younger than 40 years, and 8 were 40 years or older. The mean spherical equivalent was -10.1 ± 5.41 D; 3 eyes had a pIOL power less than -10.50 D, 4 eyes between -10.50 D and -13.50 D, and 14 higher than -13.50 D. The mean time between pIOL implantation and cataract surgery was 4.2 ± 1.8 years. No eye with implantation of the latest models (V4b and V4c) developed cataract. The mean vault distance in eyes that developed cataracts was 103 ± 69 μm.
CONCLUSIONS: The incidence of cataract was low after pIOL implantation at the 6-year follow-up. The rate of cataract was higher in older patients and in those with high refractive errors.
