Abstract Details

Purpose:

To investigate the effect of air bubble on the corneal endothelium at the end of cataract surgery

Setting:

University of Health Sciences Ulucanlar Eye Research and Education Hospital.

Methods:

In this prospective study, patients who underwent cataract surgery were divided into two groups. 60 patients with air bubble injected into the anterior chamber at the end of the operation and 46 patients without air bubble as control group were examined. Endothelial cell density (ECD), coefficient of variation (CV), hexagonality rate (6A) and central corneal thickness (CCT) measurements were analyzed by noncontact specular microscopy (Tomey EM-4000, Tomey Corp., Japan) preoperatively and on the 1st day, 1st week and 1st month after surgery. Mean ultrasound power (US), ultrasound time (UST) and effective phaco time (EFX) values of phacoemulsification were noted.

Results:

There was no significant difference in mean CDVA, ECD, CV, 6A and CCT values between the groups preoperatively (p>0.05). Intraoperative US, UST and EFX values were similar (p> 0.05). On the postoperative first day, CCT value was lower in the study group than control group (p=0.021), but the mean CCT values on the postoperative 1st week and 1st month were similar (p=0.208, p=0.394, respectively). There was no significant difference in mean CDVA, corneal edema, ACR, ECD, CV, 6A and CCT values between the groups 1 day, 1 week and 1 month postoperatively (p>0.05 for each one).

Conclusions:

Although air bubble has no detrimental effect on the corneal endothelium, no protective effect was found on the corneal endothelium.
