Correlation Between Postoperative Central Corneal Thickness and Endothelial Damage After Cataract Surgery by...

Area of Science:

• Ophthalmology
• Corneal Surgery
• Cataract Surgery

Background:

• Cataract surgery, particularly phacoemulsification, can lead to temporary corneal edema.
• Endothelial cell loss is a critical factor in corneal health post-surgery.

Purpose of the Study:

• To investigate the relationship between postoperative corneal edema and endothelial cell loss.
• To determine if corneal thickness can predict endothelial damage after microcoaxial phacoemulsification.

Main Methods:

• A prospective study included 85 patients undergoing microcoaxial phacoemulsification.
• Corneal thickness and endothelial cell density were measured preoperatively and at multiple time points post-surgery using noncontact specular microscopy.
• All surgeries were performed using the Stellaris device with 2.2-mm incisions.

Main Results:

• Mean corneal thickness increased significantly at 2 hours post-surgery but returned to near baseline by 15 days.
• Mean endothelial cell loss was 3.0% at 2 hours and reached 11% at 1 month.
• Significant endothelial cell loss (>15%) at 4 days correlated with significant immediate corneal edema (>15%).
• A significant correlation (r = 0.4, P < 0.0001) was found between immediate postoperative corneal edema and endothelial cell loss at 1 month.

Conclusions:

• Immediate postoperative corneal edema is a potential indicator of subsequent endothelial cell damage.
• Corneal thickness measurement post-phacoemulsification may serve as a valuable marker for assessing endothelial integrity.
