Graft-host vascularization occurred in 2 (12%) eyes. There was no formation of ''secondary anterior chamber'' postoperatively. These eyes were managed by injection of air or a mixture of perfluoropropane (C3F8) with air (14% C3F8, 86% air) into the anterior chamber to temporarily seal the microperforations. ![]() However, this perforation had no statistical impact on final visual acuity (p = 0.47). Intraoperative perforation of DM during DALK occurred in 2 (12%) eyes. However, crossing the two groups using the Mann Whitney test showed no statistical difference between groups (p = 0.40). This analysis indicated that astigmatism correction was statistically significant with the big bubble technique (p = 0.008) compared to manual dissection (p = 0.056). The cohort was subdivided into 2 groups based on the surgical technique and the analysis was repeated. Visual acuity increased statistically significantly from 0.9 ± 0.3 (range 0.5-1.6) preoperatively to 0.4 ± 0.2 (range 0.0-0.7) at last follow-up (p 0.05, all cases) (Table 2). The mean overall age was 31.4 ± 9.6 years (range, 1950 years). Results: The mean follow up was 14.6 ± 8.2 months (range 6-35 months). Visual acuity (Log-MAR notation), intraocular pressure, intraoperative complications and postoperative graft status were assessed. The big bubble technique was performed in 10 (62.5%) eyes and manual dissection was performed in the remaining 6 (37.5%) eyes. Baring of Descemet's membrane (DM) during DALK was achieved in 8 (50%) eyes residual stroma was left intraoperatively in the remaining 8 (50%) eyes. Methods: A retrospective review was performed in 16 eyes of 16 patients who underwent DALK at the King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia between Januand December 30, 2009. Purpose: To present the surgical outcomes of deep anterior lamellar keratoplasty (DALK) for pellucid marginal degeneration (PMD).
