[A long-term evaluation for opticfull-thickness lamellar keratoplasty]
Summary
Optic full thickness lamellar keratoplasty (OFLK) shows comparable visual outcomes to penetrating keratoplasty (PKP) with better graft transparency and endothelial cell stability. OFLK offers a promising alternative for corneal stromal disorders.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Transplantation
Context:
- Corneal stromal disorders necessitate surgical intervention for vision restoration.
- Penetrating keratoplasty (PKP) is a traditional method, but alternatives are sought.
- Endothelial function is crucial for graft survival and visual acuity.
Purpose:
- To compare the long-term optical effects of optic full thickness lamellar keratoplasty (OFLK) versus penetrating keratoplasty (PKP).
- To evaluate graft transparency, visual outcomes, and endothelial cell density in both procedures.
Summary:
- A study involving 48 eyes (25 OFLK, 23 PKP) with stromal disorders demonstrated similar visual recovery rates between OFLK and PKP.
- OFLK achieved higher graft transparency (84.0% vs. 69.6%) and better visual acuity (40.0% vs. 21.7% achieving >0.3 vision) at 2-3 years.
- Endothelial cell density remained stable in OFLK, unlike the decline observed in PKP.
Impact:
- OFLK presents comparable optical effectiveness to PKP with enhanced safety and fewer complications.
- The findings suggest OFLK is a viable and potentially superior option for specific corneal conditions.
- Further research into OFLK surgical techniques is warranted to optimize its clinical application.
