Abstract Details

Purpose:

To examine the changes in intraocular pressure (IOP) in the early period after phacoemulsification surgery in nonglaucomatous eyes

Setting:

Clinic of Ophthalmology, Clinical Centre Kragujevac, Serbia

Methods:

This prospective study was performed on 56 patients with cataracts who underwent phacoemulsification and in-the-bag implantation of a intraocular lens. Each of 56 patients received same preoperative and postoperative medication. Patients with previous eye trauma, pseudoexfoliation syndrome, glaucoma, prior intraocular surgery and those developing any complication during or after surgery were excluded. Goldmann applanation tonometry was performed by the same examiner on the day of the operation as well as 4, 24 hours and 7 days after phacoemulsification and in-the-bag intraocular lens implantation. Patients were operated by the same surgeon using clear cornea incision.

Results:

In this study 56 patients were included average age 70.43 ± 7.80. The intraocular pressure on the day of the surgery had a mean value of 15.07 ± 2.51 mmHg. Maximum was achieved 4 hours after surgery with mean values of 22.31 ± 6.13 mmHg, mean values were compared and it was found statistically significant difference (p< 0.05) Intraocular pressure after 24 hours was 18.04 ± 4.99 mmHg and also statistically significant (p < 0.05). Seven days after phacomelsification we have normalization of intraocular pressure and mean values of 16.55 ± 3.14.

Conclusions:

The intraocular pressure rise after phacoemulsification and lens implantation was detected in every eye. Spike was reached after 4 hours after surgery and after 7 days IOP was normalized. Although patients without optic nerve damage seem to tolerate transient increases in IOP without problems we must be aware and understand the various treatment options for elevated intraocular pressure. It is difficult to predict postoperatively which patients are in high risk group. It is necessary to carefully observe IOP leaps and their influence on postoperative visual acuity.
