September 2011 EW MEETING REPORTER 97 for underlying chronic pain syn- dromes as a contraindication to sur- gery. "There are a lot of patients we treat with refractive surgery that have done just fine," he said. "We'd be eliminating patients that could potentially have successful surgery, but it's certainly a possibility with these pre-existing syndromes that they could have this disabling con- dition." Dr. Cason recommended a multidisciplinary approach—for example, in conjunction with a psychiatrist—to handle these cases. Study evaluates pain with use of different bandage contact lenses The Acuvue Oasys is the most effec- tive FDA-approved bandage soft con- tact lens following PRK to reduce pain, concluded Angelletta N. McCraney, D.O., M.P.H., during her presentation of a prospective, ran- domized, double-masked study. Dr. McCraney and colleagues evaluated the post-op pain level reported for eyes using the Acuvue Oasys, Ciba Air Optix, and the Bausch + Lomb (B+L) Pure Vision (Rochester, N.Y.). "Differences in post-operative pain relief have been anecdotally noted with different contact lenses," she said. To see if this anecdotal evidence had any scientific credibility, Dr. McCraney looked at 108 eyes of 54 patients randomized to one of the three lenses. All patients were evalu- ated in the clinic on post-op days 1 and 4 with a survey determining absolute pain in each eye on a scale of 0-10. All patients were managed post-op with the standard post-PRK treatment regime including a topical antibiotic, topical steroid, artificial tears, and oral pain medication. For analysis of absolute pain, patients were grouped by pair of lenses used. On day 1, Acuvue eyes had the least number of more painful eyes at 7%, followed by Ciba with 30% and B+L with 56%. Seven percent re- ported no difference. On day 4, the Acuvue eyes had the least number of more painful eyes at 2%, followed by Ciba with 23%, and B+L with Scientific Program composed by 19 Subspecialties A subspecialty Day for Cataract, Glaucoma, Refractive Surgery, Medical Retina and Surgical Retina 140 Session Themes and 1,000 Presentation Topics for Invited Programs 600 Free Papers and Instruction Courses, 500 Posters and 40 Videos for Submitted Programs Social Events Opening Ceremony and Welcome Reception (13 April 2012) Gala Dinner (15 April 2012) The Due Date of Regul ar Regi stration i s 14 March 2012 The 27th Asia Pacific Academy of Ophthalmology Congress - The Joint Congress of APAO/SOE held in conjunction with the 107th Annual Meeting of KOS 50%. Twenty-five percent reported no difference. "The B+L lens was reported as least comfortable most often, which was statically significant," she said. "Differences in the lenses that may contribute to pain include variations in base curve diameter and oxygen permeability. The Acuvue Oasys had the lowest post-PRK pain scores. Based on this study, there is a differ- ence in post-PRK pain based on the various contact lenses that was both statistically and clinically signifi- cant. In this study, there appears to be an association with the edge pro- file and the level of comfort."
