Abstract
Dry eye is described as a state of abnormal tear film that can be caused by a number of conditions which alter its composition and affect its stability
With recent advances in cataract and refractive surgeries, postoperative dry eye has been implicated as the most important obstacle to patient’s satisfaction despite an excellent visual recovery
The purpose of this study is to detect dry eye following phacoemulsification surgery and analyze its relation to associated intra.-operative risk factors.
The diagnosis of ocular surface disease is based on the patient’s symptoms and medical history which should include questions about topical and systemic medications used and possible exposure to aggravating factors and ophthalmological examination.
Eye examination was carried out on 50 eyes of 50 patients without preoperative dry eye. Schirmer’s Test I, Schirmer’s Test II ,tear meniscus height, tear break-up time, and lissamine green staining of cornea and conjunctiva were performed preoperatively and at 1 days, 7days, 1-month, and 2 months after phacoemulsification surgery, along with the assessment of subjective symptoms. The correlations between these values and the operating microscope light exposure time along with the phaco time were investigated.
Results showed that there was a significant deterioration of all dry eye test values following phacoemulsification surgery along with an increase in subjective symptoms. These values started improving after.
