Abstract Details

Purpose:

Evaluate Corneal Coating for Cataract Surgery as compared to BSS irrigation

Setting:

POLIVISUS, via A Moro 34, Brescia, Italy, private ophthalmology clinic.

Methods:

Study included 40 cataract patients. Experimental group included 20 eyes receiving single application of eyeDRO corneal coating (Alchimia, Italy), immediately before surgery. Control group included 20 eyes with BSS-irrigation during surgery. All patients underwent phacoemulsification cataract surgery using Infinity equipment (Alcon, USA). Tear breakup time (TBUT) was measured preoperatively and 1-hour postoperatively. Surgeon scored clarity of operative field and ease of manipulation at different intervals. The applications of eyeDRO or BSS during surgery were registered. Eye transparency was examined by slit lamp (Nikon, Japan), and epithelial damage by fluorescein staining, 2 hours postoperatively. All patients filled a self-assessment questionnaire.

Results:

Preoperatively, 61% of the patients showed normal TBUT (> 10 sec). Post-peratively, 25% and 64% of the patients still showed normal TBUT in control and Eyedro-treated group respectively. Corneal transparency and operative field clarity were significantly better in Eyedro-treated group than in Control group at each time interval. Six irrigations were required on average in Control group with use of 13,6ml BSS per procedure. Two hours postoperatively, 10% and 57% of patients showed moderate fluorescein staining in Eyedro-treated and Control group, respectively. 20% of patients in Eyedro-treated reported foreign body sensation 24h postop compared to 86% in control group.

Conclusions:

Intraoperative Corneal Coating allowed to preserve normal TBUT, increase significantly the clarity of the operative field, facilitated surgical manipulation and improved patient comfort as compared to BSS irrigation procedure. Moreover it resulted in simplification of the phacoemulsification cataract surgery procedure both for the patient and operating theatre staff.
