	Dr Parag Majmudar on the Impact of Collagen Crosslinking and DMEK Dr. Parag Majmudar reviews highlights of the 2008 ASCRS meeting in a discussion with Dr. William Trattler. Corneal collagen cross-linking with riboflavin + UVA shows great potential for the treatment of ectasia and keratoconus. This has tremendous potential to treat early stage keratoconus patients so that they may be eligible for refractive procedures. Endothelial keratoplasty is another hot-topic having gone from DLEK to DSEK and possible moving to DMEK (Descemet's membrane only) in the future. Initially, his DSEK procedure followed that of Francis Price, MD, with preparation of donor tissue. Dr. Majmudar has recently switched to using pre-cut donor tissue, but finds that tissue thickness standardization is still an issue. Femtosecond technology may remedy this soon. Has used 60/40 fold, tri-fold, and glides for insertion of donor tissue into the anterior chamber. The goal is the preservation of the endothelial cell layer and ensuring better visual outcomes. DMEK is another hot topic. Pioneered by Garrit Melles, MD, DMEK is based on the idea that stromal dissection isn't required, allowing you to implant only Descemet's membrane into the anterior chamber. Using non-air gases such as octafluoropropane (C3F8), or sulfur hexafluoride (SF6) may aid in prevention of graft dislocation.
	AAO 2008 Dr Audrey TalleyRostov Shares Tips on Anterior Segment Procedures Dr. Audrey Talley-Rostov describes some of the latest trends in Cataract, Refractive, and Corneal procedures in an interview with Ryan Alfonso, MPH, of OphthalmologyWeb. Dr. Talley-Rostov describes the trend toward the use of accommodating IOLs like the Crystalens HD. She then shares tips on the preoperative counseling of presbyopic IOL patients. Dr. Talley-Rostov then defines a variety of options are available to remedy both quality and amount of vision in patients with post-operative complaints. Femtosecond assisted laser keratoplasty using the Intralase system in corneal transplantation has also been used in her practice. Matching the donor and recipient tissue geometry with the zig-zag pattern has resulted in far better outcomes (20/25 in one case, 4 months post-op). She also describes her use of intrastromal corneal ring segments in the treatment of pellucid marginal degeneration, keratoconus, post-LASIK ectasia, and even post-RK ectasia.
	Bradley Randleman, MD, Describes A New Ectasia Risk Assessment Model AAO 2008: Dr. J. Bradley Randleman discusses a new model for assessing post-LASIK ectasia risk in an interview with refractive editor David Goldman, MD. Five risk factors were identified and are discussed here. Current treatments for ectasia are reviewed and preliminary clinical trial data from studies around the world are presented.
