Abstract Details

Purpose:

To examine the changes in intraocular pressure in the early period after phacoemulsification surgery in non-glaucomatous eyes and eyes with primary open-angle glaucoma

Setting:

Clinic of Ophthalmology, Clinical Centre Kragujevac, Serbia

Methods:

The randomized prospective clinical study included 50 eyes of 50 patients with primary open-angle glaucoma (POAG) and 50 control eyes age-matched patients who underwent phacoemulsification surgery between January 2017 and June 2017. Intraocular pressure (IOP) was measured preoperatively as well as 4, 24 hours and 7 days after phacoemulsification and posterior chamber lens implantation. Each of 100 patients received same preoperative and postoperative medication and was operated by the same surgeon. The patients were operated with clear cornea incision.

Results:

Preoperatively, the mean value for POAG group was 18.16±5.15mmHg and for control group mean value was 15.06±2.41mmHg. Significant differences were found in the preoperative IOP values (p < 0.05). 4 hours after surgery IOP rise was detected in POAG group with mean values 28.00±8.30mmHg and control group 22.06±6.32mmHg.These values were also statistically significant (p<0.05). After 24 hours mean values of POAG group were 19.67±4.683mmHg and control group 17.85± 4.67 mmHg, these values show that there is no statistically significant difference between compared groups after 24 hours. (p> 0.05). 7 days after phacoemulsification further normalization of intraocular pressure was acknowledged

Conclusions:

The intraocular pressure rise after phacoemulsification and posterior chamber lens implantation was detected in every eye. A substantial rise in IOP occurred in approximately 60% of the eyes with POAG. Furthermore, since the normalization of IOP seems to occur within 24 hours after surgery, it may be prudent to measure IOP a few hours after surgery in patients with glaucoma. 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 for patients with optic nerve damage.
