To evaluate the effects of laparoscopic sleeve gastrectomy (LSG) on corneal and lens optical density in obese patients.
Approach:
Study Design: A prospective study evaluating 58 eyes from 58 obese patients undergoing LSG, measuring changes in corneal and lens optical density before and six months after surgery.
Measurement Technique: Pentacam HR Scheimpflug imaging was used to assess corneal densitometry (CD) and lens densitometry (LD).
Key Findings:
Mean body mass index decreased from 43.4 kg/m² to 31.5 kg/m² after surgery.
Corneal densitometry decreased from 15.2 to 12.9 GSU.
Lens densitometry fell from 10.9 to 9.8 GSU.
Significant reductions in intraocular pressure and central corneal thickness were observed.
Changes in corneal and lens densitometry showed a moderate positive correlation.
Interpretation:
Limitations:
Single-center design.
Modest sample size.
Short six-month follow-up period.
Lack of evaluation of molecular markers of oxidative stress.
