Summary
Cataract surgery in X-linked megalocornea (XLM) patients is feasible. Careful surgical technique and intraocular lens (IOL) selection are crucial for successful outcomes in these complex cases.
Area of Science:
- Ophthalmology
- Genetics
- Surgical Innovation
Background:
- X-linked megalocornea (XLM) is a rare genetic disorder characterized by enlarged cornea.
- Patients with XLM often present with additional ocular anomalies, complicating management.
Observation:
- A 49-year-old male with XLM and mosaic corneal dystrophy underwent bilateral cataract extraction.
- Pre-existing pseudoexfoliation of the lens capsule was noted in the right eye.
- Intraoperative observations revealed bilateral anomalies of the lens capsule and zonule.
Findings:
- Phacoemulsification with posterior chamber intraocular lens (PC IOL) implantation was performed.
- Best spectacle-corrected visual acuity of 20/20 was achieved bilaterally post-surgery.
- A slight decentration of the IOL was observed in the right eye after 13 months follow-up.
Implications:
- Cataract surgery in XLM patients requires meticulous surgical technique and appropriate IOL selection.
- Anomalies of the anterior ocular structures, including the lens capsule and zonule, are common in XLM.
- Successful visual rehabilitation is achievable, emphasizing the importance of individualized surgical planning.
