Comparison of Long-Term Outcomes of Penetrating Keratoplasty and Deep Anterior Lamellar Keratoplasty Surgery in Patients with Keratoconus: Retrospective Study

Abstract

=0.10, p2=0.12; respectively). At the end of the 5-year follow-up period, graft survival was 93.9% after PK and 100% after DALK (p=0.17). The most common complication during follow-up was increased intraocular pressure (IOP), which was 33% in patients who underwent PK and 6.5% in patients who underwent DALK (p=0.08). Conclusion: Long-term visual outcomes of PK and DALK surgeries are similar in eyes with kerato-conus. Increased IOP and graft rejection are observed more frequently after PK. DALK surgery is a safer option in terms of complications.
