Patients who undergo Descemet stripping automated endothelial keratoplasty (DSAEK) experience better postoperative corneal sensation and less tissue damage than their penetrating keratoplasty (PKP) counterparts, according to a study published in the journal Cornea. Researchers in Japan used fluorescein staining to determine corneal epithelial integrity in 31 eyes of 28 DSAEK patients and 15 disease-matched eyes of 15 PKP patients.
The results: Corneal sensation was preserved and epithelial damage was less severe in the DSAEK group. “The preservation of corneal sensation seems to contribute to the early recovery of visual function and long-term maintenance of ocular surface health after DSAEK,” researchers concluded.

Hot on the heels of the long-awaited AREDS 2 data, published in May, comes an updated version of PreserVision AREDS 2 Formula vitamin and mineral supplement from Bausch + Lomb. Initially released in 2010, the supplement was recently reformulated to contain the same levels of nutrients recommended by the newest clinical findings of the second phase of this landmark clinical study.
The newly updated supplement contains 500mg of vitamin C, 400 IU of vitamin E, 10mg of lutein, 2mg of zeaxanthin, 80mg of zinc and 2mg of copper. B+L says that this combination of nutrients has been found to assist in the prevention of AMD and improve overall ocular health.
