Abstract
Introduction: • Dry eye syndrome is a multifactorial disease characterized by dryness of the ocular surface due to tear deficiency and overevaporation. • The symptoms observed in dry eye syndrome include dryness, irritation, burning and ocular pain. • Some surgical interventions related to anterior segment may cause dry eye and aggravate the symptoms in pre-existing dry eye, like photorefractive keratectomy (PRK), Laser Assisted in Situ Keratomeilusis (LASIK), extracapsular cataract extraction (ECCE) and phacoemulsification. • Postoperative dry eye has been implicated as the most important obstacle to patient's satisfaction despite an excellent visual recovery.
Aim of the work: • Evaluate the course of dry eye after phacoemulsification.
Patients: • Prospective study carried out on one hundred eyes of one hundred patients who underwent an uneventful phacoemulsification surgery and intra ocular lens implantation and their age ranged from 40-65 years old.
Methods: All patients included in the study were subjected to the following: 1. Informed consent. 2. Full history taking with complete clinical ophthalmological examination. 3. All patients were examined before the phacoemulsification surgery and at 1st week, 1st month, 3rd month post operatively by Tear break up time (TBUT), Schirmer test II (ST-II) with anesthesia and Ocular surface disease index (OSDI) questionnaire. 4. All patients were undergone phacoemulsification and posterior chamber intraocular lens (IOL) implantation by the same surgeon using the same technique. 5. Correlations of effective phaco time and microscope light exposure time with TBUT, ST-II with anesthesia, and the OSDI score were studied.
