CXL with riboflavin is an effective procedure for children with progressive keratoconus. The results show stabilization, improvement, or both in keratoconus in terms of BCVA and corneal curvature after CXL in most children.

Purpose:The aim of this study is to describe a modified technique of vertically split-conjunctival autograft (CAG) for primary double-head pterygium and evaluate its postoperative outcome.Methods:In this retrospective, noncomparative, interventional case series, 87 eyes of 87 patients of double-head pterygium from June 2009 to June 2015 were included. They underwent vertical split CAG. A limbus-limbus orientation was not strictly maintained. Primary outcome measure was recurrence rate. Other outcome measures studied were graft retraction, Tenon's granuloma, dellen, and so on.Results:Mean age was 54.54 ± 11.51 years; M:F was 41:46. Mean follow-up was 17.28 ± 10.28 months. The only significant complication was recurrence rate of 3.45% (3 eyes out of 87). Other most common secondary outcome was graft edema, 42.52% (37 eyes out of 87) which resolved without any intervention. Other outcomes such as graft retraction (31.03%), dellen (1.15%), Tenon's granuloma (3.45%), and subconjunctival hemorrhage (36.78%) were recorded.Conclusion:Modified vertical split CAG without maintaining limbus-limbus orientation, just large enough to cover the bare scleral defect, appears to be a successful technique with lower recurrence rate in treating double-head pterygium.

Purpose:To evaluate functional and anatomical outcome in patients undergoing deep anterior lamellar keratoplasty (DALK) with intraoperative Descemet's membrane (DM) perforation (macro and micro).Methods:A retrospective cross sectional study (January 2009 to December 2015) of sixteen eyes of sixteen patients which included nine patients of advanced keratoconus (KC), two patients with paracentral DM scarring post hydrops, KC with Bowman's membrane scarring, macular corneal dystrophy and one patient of advanced Pellucid Marginal Degeneration (PMD). All underwent DALK with intraoperative DM perforation. Big bubble technique was attempted in all except in the two patients with post hydrops DM scar. Preoperative and postoperative best corrected visual acuity (BCVA), astigmatism and endothelial count (EC) were compared.Results:Postoperative BCVA and astigmatism were found to be better and statistically significant (’p value’ 0.00 and 0.003 respectively). BCVA preoperative and postoperative was 1.07± 0.3 and 0.28 ± 0.09 in LogMAR respectively and astigmatism pre and postoperative 4.14 ± 1.5 D and 2.7 ± 0.97 D respectively. Percentage decrease in EC at sixth postoperative week was 7.48% and at sixth month and 1 year postoperative was 15.1%. Two patients developed postoperative double anterior chamber and two patients developed pupillary block glaucoma and all were successfully managed.Conclusion:Not all patients of intraoperative DM perforation (including macro perforation) needs to be converted to penetrating keratoplasty. DALK can be successfully done if the perforation is identified early and managed adequately. This is the only known study which has shown a large series of successful DALK even with macro perforations.
