Clareon Intraocular Lens: Results of Cataract Surgery. Exilaser Cuenca Ophthalmological Center, Ecuador June 2020 – July 2021

Abstract

Objective: To analyze visual acuity, refractive cylinder, refractive sphere and complications in cataract surgery by phacoemulsification with Clareon intraocular lens. Methodology: A descriptive-observational, longitudinal study based on the review of medical records of the Exilaser Ophthalmology Clinic of 114 patients who underwent cataract surgery by phacoemulsification with a Clareon intraocular lens was carried out. Descriptive statistical techniques such as frequencies, measured percentages were used on those cases of central tendency and comparative analysis with T Student. Results: The most frequent pre-surgical visual acuity on the Snellen scale was 20/CD with 27.2%, the most frequent corrected pre-surgical visual acuity was 20/CD with 14.0%, the most frequent pre-surgical refractive cylinder value was 0 with 50.9%, the most frequent pre-surgical refractive sphere value was 0 with 28.9%. Post-surgical visual acuity was 20/30 with 20.2%, Corrected Post-surgical Visual Acuity was 20/20 with 53.5%, the most frequent post-surgical refractive sphere value was 0 with 40.4%, the most frequent Post-surgical Refractive Cylinder value was 0 with 14.0%. 99.1% did not present trans-surgical complications and 91.2% did not present post-surgical complications. Conclusions: Cataract surgery by phacoemulsification with CLAREON intraocular lens improves Visual Acuity and the Refractive Sphere, with statistically significant results, with minimal intra-surgical and post-surgical complications.Abbreviations: Visual acuity (VA), Visual acuity without correction (AVSC), Visual acuity with correction (AVCC), Refractive sphere (ER), Refractive cylinder (CR), Intraocular lens (IOL), Dioptres (D).
