PURPOSE: To report the surgical outcome of early lens aspiration, posterior chamber intraocular lens (PC IOL), and capsular tension ring (CTR) in a case series of microspherophakia (MSP) and secondary glaucoma.
METHODS: Case series of 18 eyes of MSP cases presented with lenticular myopia and secondary glaucoma that underwent early lens aspiration, PC IOL and CTR by one ophthalmologist. Baseline, long-term postoperative outcomes and complications were documented.
RESULTS: All cases underwent successful surgery with lens aspiration PC IOL implantation and CTR insertion without intraoperative complications. One of the 18 cases was a delayed referral which had broad anterior synechiae and following lens aspiration developed corneal decompensation. In one eye, CTR implantation was not possible hence, lens aspiration with scleral fixation (SF) of 3 piece IOL was performed (excluded from the analysis). Overall there was an improvement in visual acuity (from 0.3 ± 0.1 to 0.2 ± 0.2 LogMar, P = 0.006), intraocular pressure (IOP), and most notably, deepening of the anterior chamber. Some cases required subsequent glaucoma surgery to control IOP. After a long duration of follow-up, all cases had stable capsular lens complex and no capsular phimosis.
CONCLUSION: Early Lens aspiration with CTR and PCIOL alone in MSP with lens subluxation has a significant impact on the patient's quality of vision, deepening the anterior chamber and preventing complications or poor outcomes. In addition, good capsular-lens complex stability and absence of capsular phimosis or phacodonesis on long-term follow-up were obtained.
