Greater Satisfaction Reported With Lasik Than Contact Lenses
Compared with contact lens wear, LASIK did not significantly increase dry eye symptoms and it improved ease of night driving and resulted in higher levels of satisfaction at 1, 2, and 3 years’ follow-up, according to a study in Ophthalmology.1
Marianne O. Price, PhD, of the Cornea Research Foundation of America in Indiana, and colleagues conducted a prospective, longitudinal, parallel-group, multicenter survey of 1,800 patients, aged 18 to 60 years, who had LASIK or continued using contact lenses. Twenty sites across the United States enrolled patients who completed a study-specific baseline survey during a contact lens fitting or while being evaluated as a candidate for LASIK. Links to follow-up surveys were emailed annually for 3 years. Between-group differences were assessed by analysis of variance, and associations were assessed by logistic multivariate regression.
Of the 1,800 patients, 694 (39%) comprised the control group who continued contact lens wear, 819 (45%) wore contacts at baseline and had LASIK, and 287 (16%) wore glasses at baseline and had LASIK. Most contact lens users had worn them successfully for 5 years or longer.
The proportion of patients expressing strong satisfaction with their current vision correction method decreased from 63% at baseline to 54% at year 3 in the contact lens control group, whereas 88% of former contact lens wearers and 77% of former glasses wearers were strongly satisfied with LASIK at year 3. Patients who were 40 years of age or younger when they had LASIK were somewhat more likely to be strongly satisfied than older patients.
LASIK significantly reduced difficulties with night driving and nighttime visual disturbances among former contact lens users and former glasses wearers. The proportion of patients with dry eye symptoms at 1, 2, or 3 years after LASIK was not significantly increased relative to baseline contact lens wear but was significantly increased relative to baseline glasses use; this was consistent with many glasses users having tried and abandoned contact lenses because of latent dry eye problems. Compared with continued contact lens wear, LASIK significantly reduced self-reported rates of eye infections, ulcers, and abrasions each year.

Raindrop Near Vision Inlay Receives FDA Approval
ReVision Optics has received US FDA approval for the Raindrop Near Vision Inlay for the surgical correction of presbyopia, according to a company news release. The inlay is indicated to improve near vision by reshaping the anterior curvature of the cornea in presbyopia patients who have emmetropic refractions (1.00 to -0.50 D).
The Raindrop is the second FDA-approved implantable corneal device for the correction of near vision in patients who have not undergone cataract surgery, joining the Kamra inlay (AcuFocus), which received FDA approval in April 2015. The Raindrop is the first FDA-approved implantable device that changes the shape of the cornea to achieve improved vision, the news release said.
The approval was based on a study of 373 patients treated at 11 investigational sites in the United States. Results from the study, which were submitted to the FDA in ReVision Optics’ premarket approval application, showed clinically significant improvement in near visual performance. Average UNVA improved by 5 lines in treated eyes, and there was no loss of binocular distance vision. Ninety-eight percent of patients achieved a UNVA of 20/40 or better, and 88% of patients achieved a UNVA of 20/25 or better in the treated eye at 24 months. Mean UCVA for both eyes exceeded 20/20 at all distances. Refractive stability was achieved at 6 months.
Information provided in the premarket approval submission confirmed that the Raindrop is removable and that patients return to their baseline visual acuities if the device is removed.
Pixium Vision Gains UK Approval for Trial of Bionic Vision System
Pixium Vision has received approval from the UK Medicines & Healthcare products Regulatory Agency to initiate a clinical trial of the Intelligent Retinal Implant System (IRIS) II bionic vision system in patients who have lost sight due to retinitis pigmentosa, according to a company news release.
The IRIS II epiretinal system incorporates innovative features being evaluated, including a bio-inspired camera that is intended to mimic the functioning of the eye; an epiretinal implant with 150 electrodes; and an explantable design, minimizing the risk of retinal damage and permitting potential upgrade to newer therapy options, the news release said.
Participation of Moorfields Eye Hospital NHS Foundation trust broadens the clinical study centers of excellence, adding to sites across France, Germany, and Austria.
Pixium Vision initiated the CE Mark approval process this past December on the basis of IRIS clinical experience. Commercialization is expected to start in the second half of 2016.
Oculus Introduces Corvis ST Tonometer
Oculus introduced the Oculus Corvis ST, which combines tonometry and pachymetry with measurement of the biomechanical response of the cornea, a company news release said. According to Oculus, the Corvis ST is the first device that provides the ability to perform fast and comprehensive screenings for biomechanically weak corneas. The integration of Pentacam data allows the combination of biomechanical and tomographic data in patient screening prior to refractive surgery.
By measuring both biomechanical response and corneal thickness, the Corvis ST is able to correct for both factors at the same time and return a biomechanically corrected IOP. In addition to biomechanical screening, the Corvis ST software allows comprehensive keratoconus detection; the Corvis Biomechanical Index enables ophthalmologists to perform keratoconus screenings based on the biomechanical response of the cornea.
It is the first available screening software that combines biomechanical information with pachymetric progression data, the news release said.
Combining tomographic data from the Pentacam with biomechanical data from the Corvis ST provides improved sensitivity and specificity in the detection of patients at significant risk for developing ectasia after refractive surgery, according to Oculus. Based on these data, a tomographic biomechanical index is created, which, together with the comprehensive display, helps surgeons avoid risks and care for more patients safely, the news release said.
Positive EU Regulatory Opinion for Once-Daily Nevanac Eye Drops
The EU’s Committee for Medicinal Products for Human Use recommended the approval of once-daily Nevanac 3mg/mL (nepafenac; Novartis) eye drop suspension in Europe for the reduction in risk of postoperative macular edema associated with cataract surgery in diabetic patients, according to a company news release.
Nevanac 3mg/mL is a once-daily nonsteroidal antiinflammatory ophthalmic suspension. It is approved in Europe for prevention and treatment of pain and inflammation associated with cataract surgery. A lower concentration of nepafenac (Nevanac 1 mg/mL eye drops, suspension) is approved for both of the above indications but is administered three times daily.
