A comparison of Biofinity Energys and Air Optix plus HydraGlyde What are the differences?. Monthly replacement SiHy lenses were worn by 39 percent of the patients, and just under onethird of these were lotrafilcon B (O 2 Optix, CIBA) with a similar proportion being lotrafilcon A (Night & Day, CIBA) Balafilcon A (PureVision, Bausch & Lomb) lenses were worn by 27 percent and comfilcon A (Biofinity, CooperVision) lenses were worn by 10 percent of the patients who had been prescribed monthly replacement SiHy lenses.

Methods For the study’s contralateral eye comparison, 43 patients who underwent bilateral PRK were randomized to be fitted for a senofilcon a lens in one eye and a lotrafilcon B lens in the other The patients were masked to the specific BCL in each eye On the first 3 days after PRK, the epithelial defect size was calculated, and patients reported their level of ocular discomfort. Average reepithelialization time was 31 days for Comfilcon A and 36 days for Lotrafilcon B (p=003) Mean subjective discomfort score was 225±096 in eyes with Lotrafilcon B and 164±067 in eyes with Comfilcon A on the first exam the day after surgery and until third day the differences were statistically significant (p=0011 and p=0012, respectively).
