Acute Ocular Effects of Cigarette Smoking

Acute Effects of Cigarette Smoking on Corneal Tomographic and Biometric Parameters: A Prospective Controlled Study

Sponsor

Istanbul University

Enrollment

90 participants

Start Date

Feb 15, 2026

Study Type

OBSERVATIONAL

Conditions

Smoking, Cigarette Cornea Anterior Eye Segment Measurements

Summary

This prospective study aims to evaluate the short-term effects of smoking on corneal tomographic and biometric measurements in healthy adults. After baseline examinations and measurements are taken in both smoking and non-smoking participants, the same measurements will be repeated after 10 minutes of external exposure, and within-group and between-group changes will be compared. The aim of the study is to determine whether acute smoking exposure leads to measurable immediate changes in corneal tomographic and biometric parameters.
