Abstract Details

Purpose:

Dry eye syndrome is considered to be an inflammatory disease of the surface of the eye and as such, it may have an impact on corneal healing. It has been reported that patients who underwent phacoemulsification with intraocular lens (IOL) implantation complain of increased intensity of dry eye symptoms.The purpose of this paper is to evaluate whether a correlation between dry eye syndrome and changes in corneal topography values after cataract surgery exists.

Setting:

1 Department of Ophthalmology, Professor K. Gibiński University Clinical Center of the Medical University of Silesia, Katowice, Poland 2 Department of Ophthalmology for Adults, Ophthalmology Clinic, Katowice Division, Medical University of Silesia, Katowice, Poland

Methods:

30 patients were asked questions from Ocular Surface Disease Index (OSDI) questionnaire prior to cataract surgery. Additionally, Schirmer test I was performed to objectively assess the severity of dry eye syndrome. Anterior segment optical coherence tomography (AS-OCT), CASIA Tomey, was used to measure corneal topography prior and one day after phacoemulsification with IOL implantation. Additionally, a short medical history was recorded. The statistical analysis based on Spearman and U-Mann-Whitney tests was performed.

Results:

The study group composed of 11 males and 19 females, mean age 75 years. There was a statistically significant correlation between Schirmer test I and sum of points from the OSDI questions 1-3 (R - 0,41, p < 0,05). Statistically values of Schirmer test I were lower in patients with diagnosed glaucoma (U 28,5; p< 0,01). Patients suffering from diabetes mellitus had statistically higher values of Ks and Kf (U 27, U 48; p <0,05, respectively).There was no statistically significant correlation between OSDI/Schirmer and topography variables such as apex and thinnest corneal thickness prior and one day after surgery.

Conclusions:

Based on acquired data, the severity of dry eye syndrome does not affect changes in corneal topography during the initial period after cataract surgery. Small study group and properties of AS-OCT device stand as a major limitations of this study. Further studies have to be conducted.
