PurposeTo evaluate the indications and effects of continuously wearing the Bausch & Lomb Pure-Vision (PV)Contact Lens.MethodTwenty-nine patients (31 eyes) who required therapeutic contact lens wear were selected non-randomly from Zhongshan Ophthalmic Center for wearing (Pure Vision, PV) contact lens. Therapeutic indications included pain and irritation relief, corneal protection, and enhancement of corneal wound healing. Simultaneously antibiotics and artificial tears were used according to the ocular diseases. And then, the effect of treatment, anterior segment of eyes, contact lens fitting characteristics, lens deposits and the presence of contact lens-relative complications were evaluated.ResultsThe duration of PV contact lens wear on 31 eyes were 3-57 days, averagely 20.9 days. Patients included bullous keratopathy (6 cases, 6 eyes), keratitis incorporated with descemetocele (5 cases, 5 eyes), chemical burns with epithelial abrasions (6 cases, 7 eyes), post-keratoplasty (3 cases, 3 eyes), filamentary keratitis (3 cases, 3 eyes), corneal epithelial erosion syndrome (2 cases, 3 eyes), repetitive corneal epithelial stripping syndrome (1 case, 1 eye), corneal lamellar laceration and epithelial coloboma (1 case, 1 eye), post-extraction of traumatic cataract with durative corneal ulcer (1 case, 1 eye), post-limbal & amnia transplantation (1 case, 1 eye). For the treatment of pain and irritation relief (21 patients, 22 eyes), all patients had complete or partial relief. For corneal healing (20 patients, 22 eyes), full healing was noted in 15 patients (16 eyes) (72.7%), partial healing occurred in 4 patients (5 eyes) (22.7%). For corneal protection (21 patients, 23 eyes), lens wear was fully protective in all cases, except one case of loosely fitting. Our result shows that PV Contact Lens exhibits prominent efficiency inConclusiontreating corneal diseases and ocular surface diseases, as well as corneal protection, corneal healing and pain relief. The lens has increased oxygen transmissibility and good anti-deposit quality, reducing the risk of ocular complications. As a result of these, PV Contact Lens is the ideal bandage therapeutic lens.
