Summary
The Barraquer microkeratome enables optical lamellar keratoplasty for corneal opacification. This technique improved vision in most patients and can be combined with cataract surgery.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Vision Restoration
Background:
- Anterior corneal opacification causes visual impairment.
- Lamellar keratoplasty offers an alternative to penetrating keratoplasty.
- The Barraquer microkeratome's utility in lamellar keratoplasty requires evaluation.
Purpose of the Study:
- To assess the efficacy of optical lamellar keratoplasty using the Barraquer microkeratome for visually symptomatic anterior corneal opacification.
- To evaluate the combination of this technique with cataract surgery.
Main Methods:
- Optical lamellar keratoplasty was performed on eleven eyes of nine patients using the Barraquer microkeratome.
- Three eyes underwent combined extracapsular cataract extraction and intraocular lens implantation.
- Patient diagnoses included anterior stromal scars, Reis-Bückler dystrophy, and granular corneal dystrophy.
Main Results:
- Visual acuity improved in ten out of eleven eyes postoperatively.
- One eye showed no change in visual acuity.
- The procedure was successfully combined with cataract surgery in three cases.
Conclusions:
- The Barraquer microkeratome is effective for lamellar keratoplasty.
- Optical lamellar keratoplasty is a viable alternative to penetrating keratoplasty for selected patients.
- The technique can be safely combined with cataract surgery and intraocular lens implantation.
