COMPARISON OF VISUAL OUTCOMES OF DEEP ANTERIOR LAMELLAR KERATOPLASTY AND PENETRATING KERATOPLASTY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 71
Abstract
BACKGROUND Deep Anterior Lamellar Keratoplasty (DALK) has been used as an alternative to PK in the last few years in cases with intact endothelium, such as stromal scar, stromal dystrophies, and keratoconus. This surgical technique conserves the patient’s own endothelial cells. The present study was conducted with an aim to compare the visual outcome and various complications of Deep Anterior Lamellar Keratoplasty (DALK) and Penetrating Keratoplasty (PK). MATERIALS AND METHODS A non-randomised controlled trial of 80 cases in which either Deep Anterior Lamellar Keratoplasty (DALK) or Penetrating keratoplasty (PK) done from January 2013 to January 2016, was conducted at SMS Medical College & Hospital, Jaipur. The main outcomes measured were visual outcome, graft survival and complications. RESULTS There were not much differences between PK and DALK groups in terms of age and gender. Preoperative visual acuity in both the groups was less than 3/60. There was no significant difference between PK and DALK groups in terms of the postoperative BCVA at 1 year. BCVA was 6/24 or better in 44.73% cases in DALK group and in 40% cases in PK group. Postoperative complications were significantly more frequent after PK. CONCLUSION Visual returns of Deep Anterior lamellar Keratoplasty are comparable to that of Penetrating keratoplasty (PK) with less complications. Although the learning curve is a bit steep but being an extraocular procedure with preservation of host endothelium, it is a major advantage over Penetrating keratoplasty (PK).
