Evaluation of clinical efficacy of a three-piece intraocular lens scleral fixation in patients with lens luxation into the vitreous body

Purpose: to analyze the results and to evaluate the clinical efficacy of a three-piece MN60AC IOL scleral fixation by the Yamane method in patients with lens luxation into the vitreous body. Material and Methods. 40 patients (40 eyes) with lens luxation into the vitreous body were examined. Mean age was 63±9 years (18–82 years). Surgical treatment with implantation and scleral fixation of a three-piece IOL using the Yamane method was performed. The IOL was calculated using the Lenstar LS 900 Haag-Streit optical biometer. The IOL position was evaluated postoperatively by ultrasound biomicroscopy and the resulting refraction. Results. In the postoperative period, there was a significant improvement in the visual acuity (p=0.001). According to the refractometry data, in the postoperative period, an increase in astigmatism was detected by an average of 1 dptr with a change in its type. According to ultrasound biomicroscopy, 85 % of patients in the vertical meridian showed an IOL slope, which averaged 5.0±1.3 degrees (from 3 to 7 degrees). Conclusion. High functional results and a small number of complications prove the clinical effectiveness and safety of the three-piece IOL fixation using the Yamane method in patients with lens luxation into the vitreous cavity. For a detailed explanation of the obtained refractive results, further research is necessary with the inclusion of a larger number of patients and an increase in the follow-up period.
