Evaluation of Ocular Surface after Cataract Surgery-A Prospective Study

Area of Science:

• Ophthalmology
• Ocular Surface Disease

Background:

• Cataract surgery is a common procedure.
• The impact of cataract surgery on the ocular surface requires further investigation.

Purpose of the Study:

• To evaluate changes in tear film and ocular surface parameters after cataract surgery.
• To assess patient-reported outcomes using the OSDI questionnaire.

Main Methods:

• Prospective study of 48 eyes undergoing phacoemulsification.
• Assessed tear break-up time (TBUT), Schirmer's I test, corneal sensitivity, and corneal nerve density.
• OSDI questionnaire administered pre- and post-surgery.

Main Results:

• A significant decrease in TBUT (p=0.004), Schirmer's I test (p=0.002), and corneal nerve density (p=0.02) was observed.
• The OSDI score significantly increased post-surgery (p=0.001), indicating greater dry eye symptoms.
• No significant changes in corneal sensitivity were noted.

Conclusions:

• Cataract surgery adversely affects the ocular surface 1 month post-procedure.
• Reduced tear film quality and corneal innervation contribute to increased dry eye symptoms after surgery.
• Ophthalmologists should consider managing ocular surface health in patients undergoing cataract surgery.
