Abstract Details

Purpose:

To compare the effect of combined topical-intracameral and topical -alone anesthesia on macular thickness changes evaluated with spectral domain optical coherence tomography (SD-OCT) after uneventful phacoemulsification.

Setting:

Bal?kesir University Medical Faculty Ophthalmology Department

Methods:

This study is a prospective and non- randomized clinical trial. Seventy nine eyes of 59 healthy patients were included. All eyes were underwent standard phacoemulsification surgery under two different anesthesia type (combined topical-intracameral with 1% lidocaine: Group 1, topical -alone: Group 2). SD-OCT measurement was performed before surgery and postoperatively at 1 week and at 1 and 3 months. Cataract grade, axial length, anterior chamber depth, best corrected visual acuity and phaco parameters was also evaluated.

Results:

There was a significant increase in macular thickness of both groups for 3mm and 6mm areas at 1 week, 1 and 3 months after surgery (P<0.001) and at 1 and 3 months for central point thickness (p=0.01). In Group 1 significantly higher increment was observed in parafoveal areas of macular thickness at 1 week and 1 month when compared the Group 2 (p=0.032). There was no significant correlation between macular thickness changes and preoperative factors (age, axial length, anterior chamber depth and best-corrected visual acuity) and phaco parameters (phaco time, cumulative dissipated energy, estimated fluid used).

Conclusions:

The current study demonstrated that macular thickness significantly increased after uncomplicated cataract surgery. The most important finding was the parafoveal area seems to be more affected with combined topical-intracameral anesthesia than the topical -alone anesthesia especially at early postoperative period.
