Outcome Measures

Primary Outcomes (8)

  • 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

    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

    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

    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

    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.

    Preoperative Visit (Day -30 to Day -1), Month 1, Month 3

  • Percentage of Eyes With BCDVA Worse Than 20/40 (With BCDVA 20/20 or Better Preoperatively) at Refractive Stability

    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

    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. 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 Increase of Manifest Refractive Astigmatism Greater Than 2.00 Diopter (D) of Absolute Cylinder Compared to Preoperative Visit at Refractive Stability

    Manifest refractive astigmatism is the cylindrical portion of the subjective refraction. It is measured with ETDRS charts at a distance of 4 meters. 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 Non-flap Related Ocular Serious Adverse Events at Refractive Stability

    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. No hypothesis testing was pre-specified for this endpoint. This is a co-primary endpoint.

WaveLight EX500 excimer laser system
LASIKPROCEDURE

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.

WaveLight EX500 excimer laser system
