Purpose: To investigate the long-term characteristics and changes of presenile cataracts that had been operated in Korea.
Methods: The subjects aged from 30 to 49 years and underwent cataract surgeries at St. Mary’s hospital from 1995 to 2004 (n=976) were included in this study. Their medical records were reviewed retrospectively. Patients with histories of ocular trauma or uveitis and those received combined surgeries were excluded. Their histories of diabetes and hypertension, types of lens opacities, and preoperative and postoperative visual acuities were analyzed. Lens opacity grading had been conducted by using LOCS III. To see the change with the passage of time Cochran-Armitage proportion trend test was employed.
Results: Eyes that had surgeries for presenile cataracts over 10 years contributed 8.8%. 79.0% were male and 21.0% female. The overall mean age was 41.7 years. Among them 10.0% and 7.8% accompanied diabetes and hypertension, respectively. Eyes with anterior polar opacities, posterior subcapsular (PSC) opacities, anterior polar＋PSC opacities, cortical opacities, and nuclear opacities accounted for 35.7%, 35.1%, 7.0%, 6.0%, and 5.4% in order. 92.7% showed best corrected visual acuity more than 20/40 at 2 months after the surgery. Presenile cataracts with diabetes showed no significant increase with the passage of time (p=0.4767, CI 95%) but hypertension showed statistically significant increase (p=0.0049, CI 95%).
Conclusions: Presenile cataracts had different characteristics from senile cataracts. Men consisted of the majority of the presenile cataracts. Anterior polar opacity was the most common type of lens opacity. Cataracts with hypertension showed overall increase over 10 years.
