Abstract Details

Purpose:

To evaluate changes of central corneal thickness (CCT), subjective refraction and objective refraction 1 week after cataract surgery.

Setting:

Pauls Stradins University Hospital

Methods:

This was prospective, consecutive case series study of 20 eyes undergoing uneventful cataract surgery in a single university hospital. Central corneal thickness was measured with Heidelberg Spectralis Optical Coherence Tomography (OCT). Evaluations of subjective refraction were done before the surgery and on follow-up visits after the first week. Corneal swelling was determined as the percentage change in CCT after the surgery. Automated refraction was done on follow-up visits after week 1. Informed consent was obtained in all cases. All data were analyzed by SPSS 20.0.

Results:

Enrolled 20 eyes of 20 patients with the mean age 72.86�Â�±8.28 years, 70.0% were females and 30.0% were males. The mean CCT was 535.5�Â�±29.58 �Â�µm, after 1 week �â�€�“ 577.55�Â�±37.31.56�Â�µm. The average changes of CCT 1 week after cataract surgery was 7.66�Â�±5.37%. The average subjective refraction was 0.24�Â�±0.11 at the baseline visit. One week after surgery, BCVA was 0.68�Â�±0.2. Before surgery plus spherical lenses were used in 5.0%, after a week �â�€�“ in 20.0% of all cases. After 1 postsurgical week automated spherical refraction was �.3�Â�±0.81D. In addition, automated cylindrical refraction was -0.59�Â�±1.08D.

Conclusions:

One week after phacoemulsification CCT increased for about 7.66%. Although in most of the cases corneal edema was seen, subjective and objective refraction was highly improved in the end of the first postsurgical week. Tendency to hyperopia and astigmatism of eyes was seen in the end of the first week after phacoemulsification.
