PURPOSE: To assess intraocular pressure (IOP) before and after 1 day, 3 days, 1 week, 1 month, 3 months, 6 months and 1 year in normal eyes submitted to a phacoemulsification. METHODS: Intraocular pressure retrospective analyses (measured by Goldmann applanation tonometer) of 221 normal eyes of 133 patients submitted to an uneventful phacoemulsification. The IOP was evaluated before and after phacoemulsification ( 1day, 3 days, 1 week, 1 month, 3 months, 6 months and 1 year), and these values were submitted to a comparative analyses. RESULTS: The mean preoperative IOP of 16,06±2,69 mmHg rose postoperatively to 18,76±5,96 mmHg at 1 day; dropped to 14,82±4,08 mmHg at 3 days; 14,03±3,06 mmHg at 1 week; 13,88±3,26 mmHg at 1 month; 12,74±2,45 mmHg at 3 months; 12,74±2,01 mmHg at 6 months; and 13,24±2,77 mmHg at 1 year. The IOP rise was 18,9% at 1 day; fall of 6,9% at 3 days; 12,3% at 1 week; 12,5% at 1 month; 19,3% at 3 months; 20,1% at 6 months; and 19,9% at 1 year. CONCLUSION: In normal eyes, uneventful phacoemulsification reduced IOP. The greatest IOP decreases were in patients with a higher preoperative IOP.
