Introduction. To compare the safety and efficacy of the Therapeutic Hyper-CL™ lens versus a standard bandage contact lens (PureVision B&L) for chronic corneal edema. Methods. Prospective, multicenter, randomized, crossover study. Chronic corneal edema patients were randomized to one of two arms. The first arm was fitted with the Therapeutic Hyper-CL™ lens while the second arm was fitted with a standard soft bandage contact lens. Both arms were treated with 5% sodium chloride 6 times a day. After a 7-day treatment period, there was a 7-day washout period, after which the arms were crossed over. Patients were evaluated at days 0 (baseline), 7 (following first treatment allocation), 14 (following washout), and 21 (following second treatment allocation). The primary outcomes were 3 lines of BCVA (best corrected visual acuity) improvement. Results. In total, 49 patients were enrolled. There was significantly greater BCVA improvement rate >3 lines (30.4% versus 17.4%, P=0.04) in the Therapeutic Hyper-CL™ lens group. The mean change in BCVA lines was significantly greater for the Therapeutic Hyper-CL™ lens (3.4 ± 6.7 versus 0.9 ± 2.3, P=0.02). Conclusions. The Therapeutic Hyper-CL™ lens was associated with a higher chance for significant visual acuity improvement when compared to a standard bandage contact lens combined with 5% sodium chloride. This trial is registered with NCT02660151.

Background and Objective: Verofilcon A (PRECISION1®; Alcon) silicone hydrogel daily disposable contact lenses were designed to address clinical issues associated with new wearer discontinuation, including vision quality, sustained comfort, and ease of handling. The present study assessed the objective and subjective performance of verofilcon A contact lenses in subjects needing optical correction for refractive ametropia. Material and Methods: Subjects aged 18 years and older with non-diseased eyes, a history of successful soft contact lens wear for distance correction in both eyes during the previous 3 months, and a best spectacle-corrected visual acuity of 20/25 or better with a manifest cylinder of ≤ 0.75 diopters in each eye were recruited. The primary endpoint was distance visual acuity. Secondary endpoints included subjective ratings of overall vision, comfort, and handling, and safety endpoints included adverse events and biomicroscopy/slit lamp examination findings. Results: This study recruited 70 subjects (140 eyes), aged 20–48 years, who were predominantly white (93%), non-Hispanic/Latino (94%), and female (73%); one subject discontinued due to a change in residence. Of the 140 eyes, 132 (94.3%) had 20/20 or better vision with their habitual contact lenses. Similarly, of the 138 eyes that completed the study, 136 (98.6%) had 20/20 or better vision at dispensation of verofilcon A lenses and 132 (95.7%) had 20/20 or better vision at 3 months. Mean ± SD subjective ratings of overall vision, overall comfort, and overall handling, each on a 10-point scale, were 9.4 ± 0.8, 9.4 ± 0.8, and 9.2 ± 1.3, respectively, at lens dispensing, and 9.4 ± 0.9, 9.5 ± 0.8, and 9.2 ± 1.0, respectively, at 3 months. Mean ± SD daily wear times at 1 week and 3 months were 14.71 ± 1.85 and 15.05 ± 1.27 hours, respectively, with 68.1% at 1 week and 73.9% at 3 months wearing verofilcon A lenses for 14–18 hours per day. None of the subjects experienced a serious adverse event or discontinued lens wear, with biomicroscopy/slit lamp examination showing no evidence of corneal edema or chemosis. Conclusion: Subjects wearing verofilcon A lenses had visual acuity similar to that when wearing their habitual lens. Verofilcon A lenses were highly rated for vision quality, comfort, and handling. Verofilcon A lenses may be an option for subjects with refractive ametropia who desire lenses that can be worn for >14 hours per day and are easy to handle.

Study Results

Currently phacoemulsification (PE) is the main technique of cataract surgery, which provides for patients early clinical and functional rehabilitation. Post-operative corneal edema is a frequent and undesirable clinical situation. The purpose of the study was to evaluate clinical efficacy of 3% sodium chloride (“Ocusaline”) treatment in patients with corneal edema in the early post-operative period. Materials and methods. 60 patients (65 eyes) with post-operative corneal edema were included in the study. The main group consisted of 35 eyes; 30 eyes were included into the control group. Patients in the group 1 in addition to the routine post-operative treatment were treated with 3% sodium chloride hypertonic eye drops (“Ocusaline”); and patients in group 2 were treated according to the standard protocol. In all patients before and after surgery (in 1 day, 7 days and 1 month), subjective and objective indices of functional ophthalmic state (visual acuity, pachymetry in the central area and in the tunnel incision zone) were estimated. Results. The study results demonstrated that 3% sodium chloride hypertonic solution use facilitates visual acuity improvement due to the decrease of corneal thickness in the central area already at one week after surgery. The use of “Ocusaline” in the early post-operative period allows to decrease clinical and functional rehabilitation terms and to reduce subjective complaints of patients.
