Purpose
The aim of our study was to investigate intraocular pressure (IOP) changes following resident performed cataract surgery by comparing preoperative and postoperative day 1 IOP on one hand, and preoperative and postoperative 1-week IOP on the other. We also tried to determine variables, which influence postoperative day 1 IOP.
Setting
Cataract surgery is the most performed surgical operation in ophthalmic practice worldwide. Early postoperative IOP elevation has been a frequently reported acute adverse event. Its reported incidence has varied significantly, depending on the chosen method of lens removal and definition of IOP elevation. In most cases, the IOP returns to baseline within a few days without harmful effects.
Methods
We conducted a prospective study involving consecutive adult patients who underwent cataract extraction surgeries in the month of February 2023, at the Adult ophthalmology Department of the 20 August University hospital in Casablanca. Preoperative, perioperative, and postoperative data were gathered for all surgeries. Preoperative and 1-week postoperative IOPs were measured using calibrated Goldmann applanation tonometer. Postoperative day 1 IOP was measured within 24 h of surgery, using non-contact air puff tonometer. In this study, we defined a significant increase in postoperative IOP as a an IOP 7 to 15 mm Hg greater than the preoperative IOP value.
Results
50 cases were incuded. 78% were phacoemulsifications and 22% extracapsular cataract extractions, all performed by residents. As for the IOP changes: 30% had a significant IOP elevation in the 24 hours following surgery. Overall, IOP at 1 day after surgery (19.6±4.3) was higher than IOP before surgery (14.2±2.6), while it did not reach a statistical significance (P=0.109), with an increase of 27.5% (ΔIOP= 5.4±4.2). As for the IOP at 7 days (13.2±2.2), it was significantly lower than that before surgery (P=0.03), with a decrease of 7.7% (Δ IOP=1.1±2.3). Variables such as glaucoma, pseudo-exfoliation syndrome and axial length were not found to be significantly associated with the postoperative increase in IOP (P=0.94, P=0.26 and P=0.45).
Conclusions
In summary, increased IOP on the first postoperative day following cataract surgery occurs frequently. Understanding the variables that may be associated with an increased likelihood of an elevated postoperative IOP will help in preventing and treating this transient but potentially harmful complication.
