The Effects of Metabolic and Bariatric Surgery on the Anterior Segment Parameters of the Eye.

Abstract

Purpose: This study aimed to investigate the effects of metabolic and bariatric surgery (MBS) on the corneal and anterior segment parameters of the eye.

Materials and methods: In this study, the anterior chamber depth, volume, angle and central corneal thickness of obese patients who underwent laparoscopic sleeve gastrectomy surgery were prospectively examined using Pentacam topography before and six months after surgery.

Results: A total of 112 eyes of 56 individuals, including 26 males with a mean age of 38.88 ± 7.00 years and 30 females with a mean age of 40.94 ± 7.76 years, were evaluated (p = 0.310). Six months following MBS, the average body mass index (BMI) in men decreased from 45.5 kg/m² to 34 kg/m² (p < 0.001), and the BMI decreased from 47 kg/m² to 33 kg/m² (p < 0.001) in women. Central corneal thickness and intraocular pressure decreased significantly in both men and women. The anterior chamber depth, volume and angle ​​significantly increased six months after surgery (p < 0.001 for all parameters). A statistically significant negative correlation was observed between postoperative BMI and anterior chamber depth, volume and angle in both sexes (p < 0.001 for all).

Conclusion: This study revealed that anterior segment values, intraocular pressure, and corneal thickness may change after MBS. Caution should be exercised when evaluating for cataracts and refractive surgery after MBS.
