Clinical spectrum of bilateral microspherophakia and risk factors associated with poor visual outcomes following lensectomy surgery - A multicentric study

PURPOSE: To study the clinical profile of patients with microspherophakia and the factors associated with poor vision following lensectomy surgery. METHODS: A multicenter, retrospective, cross-sectional analysis was conducted from January 2010 to June 2022 on patients diagnosed with microspherophakia. RESULTS: A total of 102 eyes from 51 patients were enrolled, of whom 24 (47.1%) were male and 27 (52.9%) were female. All patients presented with bilateral involvement. The most common presenting complaint was defective vision, affecting 98 (96.1%) eyes. Patients exhibited varying degrees of lenticular myopia, with a mean refractive error of -13.54 ± 11.92 D. Glaucoma was present in 36 (35.3%) eyes at presentation. Subluxation of the crystalline lens was observed in 50 (49.1%) eyes, dislocation of the lens into the anterior chamber in 24 (23.5%) eyes, and dislocation into the vitreous cavity in 4 (3.9%) eyes. Limbal or pars plana lensectomy was performed in 54 (52.9%) eyes. The mean corrected visual acuity improved from 1.05 ± 0.82 logMAR units to 0.82 ± 0.79 logMAR units after lensectomy ( P = 0.029). Poor postoperative visual acuity (less than 20/200) was associated with poor preoperative visual acuity ( P = 0.005), presence of glaucoma at the first visit ( P = 0.013), and intraocular pressure >30 mmHg ( P < 0.001). CONCLUSION: Microspherophakia is associated with high lenticular myopia, subluxation, and dislocation of the crystalline lens. Significant improvement in postoperative vision was observed after lensectomy. Factors associated with poor postoperative vision included poor preoperative corrected vision, presence of glaucoma, and high intraocular pressure.
