AI Article Synopsis
- The study aimed to identify key factors that affect visual acuity after cataract surgery in patients with high myopia.
- Using data from 940 eyes with long axial lengths, researchers conducted a regression analysis to pinpoint significant factors influencing postoperative vision.
- Five main factors were found: axial length, age, corneal opacity, corneal refractive power, and history of retinal detachment surgery, with the predicted and actual visual acuities showing a significant correlation.
Article Abstract
Purpose: To identify the factors predicting visual acuity after cataract surgery in patients with high myopia.
Setting: Departments of Ophthalmology, Showa University School of Medicine and Showa University Fujigaoka Hospital, Kanagawa, Japan.
Methods: Stepwise regression analysis was used to identify the factors determining the visual acuity in 940 eyes with an axial length of 27.0 mm or longer having cataract surgery. Using a formula derived from the stepwise regression analysis, the predicted postoperative visual acuity was compared with the actual value measured in another group of 104 eyes.
Results: Five factors were identified to significantly determine postoperative visual acuity: axial length, age, corneal opacity, refractive power of the cornea, and history of retinal detachment surgery. There was a significant relationship between predicted and actual postoperative visual acuities (r = .51, P < .001). Postoperative visual acuity was similar in 63% of cases.
Conclusion: The results showed that at least five factors determine visual acuity after cataract surgery in patients with high myopia.
