Short-Term Effects of Cigarette Smoking on Corneal Measurements in Healthy Adults A Controlled Prospective Study Using Pentacam Imaging

What this Trial Is About

Researchers are investigating the immediate effects of cigarette smoking on the corneas structure and measurements in healthy adults aged 18 to 60 years. This prospective, controlled study compares smokers and non-smokers to see if short-term smoking causes measurable changes in corneal tomography and biometric parameters. The study includes 46 smokers and 46 non-smokers to better understand how acute smoking exposure might affect eye health. Participants are divided into two groups active smokers and non-smokers. Both groups undergo initial full eye examinations and measurements using a Pentacam device focused on the right eye to avoid data overlap. After baseline measurements, participants spend 10 minutes outdoors under standard conditions smokers smoke during this period while non-smokers do not. The same eye measurements are taken immediately after this exposure period to compare changes within and between the groups. Throughout the study, participants undergo detailed eye exams and Pentacam imaging to measure corneal thickness and densitometry at the pupil center before and after the smoking or non-smoking exposure. Researchers monitor changes in these parameters to assess the acute impact of smoking on eye structures. The study duration includes baseline assessment, the 10-minute exposure period, and immediate post-exposure measurements to capture short-term effects.
