Abstract
RIVERO ROMERO, Stephanie Gabriela and QUISPAYA QUISPE, Rolando. Nd-Yag Laser Capsulotomy in Pseudophakics with OCP. Gac Med Bol [online]. 2023, vol.46, n.1, pp.77-80. Epub June 01, 2023. ISSN 1012-2966. https://doi.org/10.47993/gmb.v46i1.637.
One of the causes of decreased vision is cataract. Treatment is removal of the cloudy lens with replacement by an intraocular lens (IOL). Posterior capsule opacity (PCO) is a common long-term complication. Modifications in the design of the IOL both in terms of material and shape are of greater importance in preventing PCO. Treatment is neodymium YAG laser capsulotomy.
Objective:
to identify the PCO related to the type of IOL implanted in pseudophakic patients in the FBO, from March 2019 to February 2022.
Methods:
observational study, analytical type, historical cohort subtype, retro-prospective and longitudinal, with a quantitative statistical analysis approach.
Results:
the female gender predominated with 60% and 41% represented the male; 60.3% of the total was between 65 and 80 years old. PCO in the 3 types of intraocular lenses (acrylic and PMMA) caused a decrease in visual acuity: 37%, predominated, due to the hydrophobic IOL, 36% due to the PMMA IOL and we highlight that 27% was due to the hydrophilic IOL. The incidence of PCO at 5 years was 32%. No adverse effect was recorded in our study.
Conclusion:
PCO causes mild to moderate visual acuity loss in all 3 types of IOLs; with a minimal predominance of mild AVB for the hydrophobic IOL type compared to the hydrophilic one. In addition, after capsulotomy, a large percentage has between 20/20 and 20/25 better corrected visual acuity.
