Microspherophakic lens are small with weak zonules, leading to clinical manifestations of high myopia, progressive subluxation and/or dislocation, and glaucoma either pupillary block or angle closure.
A 36-year-old patient with bilateral nonsyndromic microspherophakia re-presented with blurred vision; 6 years after, he had undergone prophylactic bilateral laser peripheral iridotomy (LPI) and a right eye trabeculectomy with mitomycin C for unrelated secondary glaucoma (due to anterior uveitis), which complicated his clinical course. When examined, his best corrected visual acuity was 20/40 and 20/50 in the right and left eyes, respectively, with -12.0 dioptre sphere; slit-lamp examination revealed irregular depth of anterior chamber bilaterally with patent LPI. A diffuse bleb was seen in the right eye. Intraocular pressure (IOP) was recorded as 16 and 14 mmHg, respectively. On dilatation, sparse zonules were visible; progressive subluxation was seen, but dislocation was prevented by sentinel zonules [Figure 1], still hanging on to the lens. Rest of the examination of both eyes was within normal limits, including discs and visual fields.
Patient underwent a lensectomy via the anterior route with intrascleral haptic fixation of a posterior chamber intraocular implant (sclera-fixated IOL) in each eye, accomplished by a glaucoma surgeon.,,
Patient achieved 20/20 vision in both eyes unaided; N6 with an addition of + 2.50. IOP was controlled with a functioning bleb in the right eye. Other than mild vitreous haemorrhage, no other serious complications were seen in the follow-up period.
To conclude, a regular vigil is essential to prevent posterior dislocation of a microspherophakic lens, enabling an anterior segment approach in its management, thereby avoiding the skill, cost, and potential complications of a posterior approach.
