This is a multicenter study to evaluate the clinical performance of the SynergEyes A2 lens in patients with refractive errors with or without astigmatism.
Hybrid contact lenses have been previously shown to be a safe and effective method to correct refractive errors with and without astigmatism. The hybrid contact lens design may provide greater visual acuity and comfort than other soft or rigid gas permeable (RGP) lenses currently available. The purpose of this study is to confirm the design of the SynergEyes A2 lens by evaluating clinical performance and, if necessary, modify certain lens parameters in order to optimize lens performance. Objective and subjective parameters will be used to evaluate the lens.

The purpose of the study is to demonstrate that the SynergEyes SA Hybrid Contact Lens clinical performance is substantially equivalent to that of the SynergEyes A Hybrid Lens when studied:...
The purpose of this trial is to evaluate the factors affecting comfortable contact lens wear and how those factors affect contact lens replacement frequency.
A refractive error is the most common reason for reduced visual acuity. Myopia, hyperopia, astigmatism and presbyopia belong to the four basic refractive errors and, unfortunately, cannot ...
This study will be done with subjects who already habitually wear scleral contact lenses. The study lens is made with a material that is already widely available and has a new design. It w...
This study seeks to evaluate the clinical and subjective performance of a new daily disposable soft contact lens.
To compare the visual-related quality of life in myopic subjects with different refractive treatments such as continuous wear of silicone-hydrogel contact lenses (CL), corneal refractive therapy (CRT)...
The aim of this study was to analyze the bacterial and fungal microbiota found in contact lens cases among two groups of patients to correlate the data on the habits of contact lens users and to evalu...
To investigate the ocular surface of an aged population wearing a daily disposable contact lens (CL) over their 1st day of wear.
The population of soft contact lens wearers is increasing, thus the issues of feeling comfortable and contact lens-induced clinical symptoms are concerned. Both lysozyme deposition and mechanical fric...
Early diagnosis of clinical markers of contact lens discomfort can help clinicians set realistic expectations and monitor and provide prophylactic management for contact lens wearers.
Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.
An alternative to REFRACTIVE SURGICAL PROCEDURES. A therapeutic procedure for correcting REFRACTIVE ERRORS. It involves wearing CONTACT LENSES designed to force corrective changes to the curvature of the CORNEA that remain after the lenses are removed. The effect is temporary but is maintained by wearing the therapeutic lenses daily, usually during sleep.
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
A procedure to surgically correct REFRACTIVE ERRORS by cutting radial slits into the CORNEA to change its refractive properties.
Instruments for RETINOSCOPY that determines the refractive state of the EYE, such as the degree of NEARSIGHTEDNESS; FARSIGHTEDNESS; or ASTIGMATISM. In principle, a retinoscope provides a light source to illuminate the RETINA, and then locates the aerial image of the retina in space to obtain an index of the refractive quality of the patient's lens system.
