  2. Introduction • Many studies about senile cataract : aged more than 60 years old : age is one of the most important risk factors of cataract • Presenile cataract patients may display different characteristics from senile cataract patients Purpose • To investigate the long-term characteristics and changes of presenile cataracts that had been operated in Korea.

  3. Inclusion criteria ① aged from 30 to 50 years ② underwent cataract surgeries at St. Mary’s hospital from 1995 to 2004(n=976) Exclusion criteria ① patients with histories of ocular trauma or uveitis ② those received combined surgeries Retrospective review of medical records Analyze ① age & sex : 31-40, 41-50 group ② their histories of diabetes and hypertension ③ types of lens opacities ④ preoperative and postoperative visual acuities Materials & Methods • Lens opacity grading : LOCSⅢ • (Lens Opacity Classification System III) • Statistical analysis • : Cochran-Armitage proportion trend test

  7. Results *PSC : posterior subcapsular *c : with *AREDS : Age-related Eye disease Study *LOCSⅢ : Lens Opacities Classification System Ⅲ *cat. : cataract *JCCESG : Japanese Cooperative Cataract Epidemiology Study Group *WCGS : Wilmer cataract grading scheme

  8. Results • Eyes that had surgeries for presenile cataracts displayed statistically significant decrease(p = 0.0002, CI 95%) • Presenile cataracts with diabetes showed no significant trend with the passage of time(p = 0.4767, CI 95%) • Presenile cataracts with hypertension showed statistically significant increase (p = 0.0049, CI 95%)

  9. Conclusion • Presenile cataract patients had different characteristics from senile cataract patients. • Men consisted of the majority of the presenile cataract patients. • Anterior polar opacity was the most common type of lens opacity. • Cataracts with hypertension showed overall increase over 10 years.
