Changes in choroidal and foveal retinal thickness after cataract surgery: Our results.

INTRODUCTION

Cataract surgery is the most common ophthalmic surgical procedure worldwide. In addition, the retina and choroid are the tissues most susceptible to damage during cataract surgery. However, conflicting results have been found about the relationship between choroidal thickness (CT), retinal thickness (RT), and cataract surgery.

AIM: To evaluate the changes in CT and foveal retinal thickness (FT) following cataract surgery in standardized conditions.

METHODS

Twenty eyes from 20 patients who experienced uneventful cataract surgery and twenty eyes from 20 age- and sex-matched healthy volunteers were recruited in the study. Optical coherence tomography measurements were obtained for 1 day, 1 week, and 1 month postoperatively and compared with the preoperative and control values. The main outcome measure was through the mean change in CT and FT.

RESULTS

The FT values did not change throughout the follow-up. A statistically significant increase in CT at the macular (P = 0.003) and temporal 1 mm region (P = 0.04) was observed at 1 week following the surgery. However, it decreased to nearly preoperative values at 1 month postoperatively.

CONCLUSION

Although the FT remains stable following uneventful phacoemulsification, the CT changes minimally in the early postoperative period. However, this effect is transient and does not appear to be clinically significant in routine conditions.
