While 2015 may not have been the year for ground-breaking introductions or trials in the field of refractive surgery, plenty of improvements have kept the procedure an evolving process, Ophthalmology Times editorial advisory board members said.
Corneal inlays to correct refractive errors are not new—various materials have been tried for more than 50 years to correct blurred vision. The greatest barriers to success of corneal inlays have been a lack of biocompatibility with the cornea, the difficulty of placing them within the corneal stroma safely, and refractive predictably.
According to several presentations given during the American Society of Cataracts and Refractive Surgery 2014 meeting, the investigational Raindrop (ReVision Optics) transparent hydrogel corneal inlay has shown to be consistently effective for the correction of presbyopia, is relatively easy to implant, and has high patient satisfaction.
A corneal inlay (Kamra, AcuFocus) for presbyopia seems to be a good treatment option for emmetropic and ametropic presbyopic patients, as well as for presbyopic patients who underwent a previous LASIK procedure, said Minoru Tomita, MD, PhD.
