Objective:
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.
