PURPOSE: To determine the incidence of hypotony or intraocular pressure (IOP) spikes in the early period after clear corneal phacoemulsification in normal and glaucomatous eyes. METHODS: This retrospective analysis comprised 112 eyes that had clear corneal phacoemulsification. Postoperative IOP measurements were collected 30 minutes, one day, and one month after surgery. RESULTS: Twenty-three eyes had an IOP of 5 mmHg or below 30 minutes postoperatively. The IOP at 30 minutes was lower than at one day in both the normal and the glaucoma group. The mean IOP in the normal group was 10.0 ± 4.3 (SD) mmHg at 30 minutes and 9.6 ± 4.4 mmHg at one day (p ≤ 0.005). The means in the glaucoma group were 9.6 ± 3.9 and 16.9 ± 5.7 mmHg, respectively (p ≤ 0.0002). The IOPs at 30 minutes and one day were not significantly different between the two groups. CONCLUSIONS: A significant percentage of eyes with clear corneal phacoemulsification had an IOP of 5 mmHg or less 30 minutes after surgery. Even though there were no postoperative complications from hypotony, and there was a relative absence of significant IOP elevation one day postoperatively, the frequency of low IOP at 30 minutes suggest that consideration be given to leaving postoperative eyes with a higher IOP at the complication of phacoemulsification, rather than with the estimated 10 mmHg tactile IOP strived for in this study.
