Summary
This study presents a combined approach for treating cataracts and corneal ectasia using corneal allogeneic intrastromal ring segment (CAIRS) transplantation and cataract surgery. The combined procedure improved visual acuity and patient satisfaction.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Cataract Surgery
Background:
- Corneal ectasia presents challenges in cataract surgery planning.
- Combined surgical approaches are being explored for complex ophthalmic conditions.
Observation:
- A 75-year-old male with cataract, high myopia, and corneal ectasia underwent combined surgery.
- The procedure involved femtosecond laser creation of a corneal pocket, cataract extraction with intraocular lens implantation, and CAIRS transplantation.
Findings:
- Postoperative examination at 3 months showed improved uncorrected and corrected distance visual acuity.
- Topographic parameters of the cornea also improved.
- The patient reported high satisfaction with the surgical outcome.
Implications:
- Immediate sequential CAIRS transplantation and cataract surgery is a potentially viable option for managing co-existing conditions.
- This combined approach may offer a solution for visual rehabilitation in patients with corneal ectasia and cataracts.
- Further research could validate this technique in a larger patient cohort.
