Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Qualified subjects will receive treatment in both eyes and be followed for 1 year. Subjects will be asked to attend a total of 9 visits (Screening, Day 0 Surgery, Day 1, Week 1, Month 1, Month 3, Month 6, Month 9, and Year 1). The primary endpoints will be assessed at refractive stability, defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at 3 months after surgery when compared with the 1-month visit) that meets all the protocol-specified stability requirements. Total expected duration of subject participation is approximately 1 year. This study will be conducted in the United States.

Experimental: WaveLight EX500 excimer laser system
Laser-assisted in situ keratomileusis (LASIK) surgery using the WaveLight EX500 excimer laser with InnovEyes software in conjunction with InnovEyes sightmap
Device: WaveLight EX500 excimer laser system with InnovEyes sightmap
FDA approved stationary scanning-spot excimer laser system used during refractive surgery for the treatment of myopia, myopic astigmatism, hyperopia, hyperopic astigmatism, and mixed astigmatism. For this clinical study, the WaveLight EX500 software will be upgraded to include the InnovEyes treatment.
Procedure: LASIK
Procedure that reshapes the front part of the eye (cornea) so that light traveling through it is properly focused on the back part of the eye (retina). The procedure will be performed using the WaveLight EX500 excimer laser system and data obtained from the InnovEyes sightmap.
Device: InnovEyes sightmap
Non-contact ophthalmic diagnostic device that captures images of the eye and collects ocular data preoperatively to generate a patient-specific ablation profile for refractive correction surgery

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Eyes With Uncorrected Distance Visual Acuity (UCDVA) of 20/40 or Better (in Eyes With Preoperative Best Corrected Distance Visual Acuity (BCDVA) of 20/20 or Better) at Refractive Stability
Time Frame: Preoperative Visit (Day -30 to Day -1), Month 1, Month 3
Visual acuity (VA) was assessed using Early Treatment of Diabetic Retinopathy Study (ETDRS) charts at a distance of 4 meters and reported in Snellen, where 20/20 indicates normal distance eyesight. Preoperatively, VA was assessed with correction in place. Postoperatively, VA was assessed with no correction in place. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A higher percentage indicates a better outcome. Both eyes contributed data to this analysis. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.
Preoperative Visit (Day -30 to Day -1), Month 1, Month 3
Percentage of Eyes With Manifest Refractive Spherical Equivalent (MRSE) Within +/- 0.50 Diopter (D) at Refractive Stability
Time Frame: Month 1, Month 3
A manifest refraction (manual refraction) was performed using a phoropter. The spherical equivalent was calculated by adding the sum of the sphere power with half of the cylinder power and reported in diopters. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive Stability was considered to be achieved at the Month 3 visit. A higher percentage indicates a better outcome. Both eyes contributed data to this analysis. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.
Month 1, Month 3
Percentage of Eyes With MRSE Within +/- 1.00 D at Refractive Stability
Time Frame: Month 1, Month 3
A manifest refraction (manual refraction) was performed using a phoropter. The spherical equivalent was calculated by adding the sum of the sphere power with half of the cylinder power and reported in diopters. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A higher percentage indicates a better outcome. Both eyes contributed data to this analysis. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.
Month 1, Month 3
Percentage of Eyes That Achieve Refractive Stability Assessed as Change From Baseline in MRSE of Equal to or Less Than 1.0 D
Time Frame: Preoperative Visit (Day -30 to Day -1), Month 1, Month 3
A manifest refraction (manual refraction) was performed using a phoropter. The spherical equivalent was calculated by adding the sum of the sphere power with half of the cylinder power and reported in diopters. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A higher percentage indicates a better outcome. Both eyes contributed data to this analysis. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.

VA was assessed using ETDRS charts at a distance of 4 meters with correction in place. BCDVA was measured in Snellen, where 20/20 indicates normal distance eyesight. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A lower percentage indicates a better outcome. Both eyes contributed data to this analysis. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.
Day -30 to -1 (preoperative), up to Month 3
Percentage of Eyes With BCDVA Loss of 2 Lines (10 Letters) or More From Preoperative Visit at Refractive Stability
Time Frame: Day -30 to -1 (preoperative), up to Month 3
VA was assessed using ETDRS charts at a distance of 4 meters with correction in place and measured in logarithm Minimum Angle of Resolution, where each line on the letter chart represents 0.1 Snellen and 0.0 logMAR equates to 20/20 Snellen, or normal distance eyesight. Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A lower percentage indicates a better outcome. Both eyes contributed data to this analysis.

Percentage of Eyes With Non-flap Related Ocular Serious Adverse Events at Refractive Stability
Time Frame: Up to Month 3
An adverse event was defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory findings) in subjects, users or other persons, whether or not related to the investigational medical device (test product). Refractive stability was defined as the latter of two postoperative manifest refractions performed at least 3 months apart (or at Month 3 after surgery when compared with the Month 1 visit) that meets all the protocol-specified stability requirements. Refractive stability was considered to be achieved at the Month 3 visit. A lower percentage indicates a better outcome. Both eyes contributed data to this analysis.
