PRIMARY outcome
Timeframe: 12 monthsPopulation: The number of eyes available for manifest refraction spherical equivalent assessment at 12 months were included in the analysis.
Manifest refractions (eyeglass prescriptions) have three components: sphere, cylinder, and axis. Sphere and cylinder are both expressed in diopters, which is a continuous measure of the focusing power needed to make the image sharp on the retina. Manifest refraction spherical equivalent (MRSE) is equal to sphere + ½ x cylinder. It is expressed in diopters (D).

PRIMARY outcome
Timeframe: Month 1, Month 3Population: There were 139 eyes with manifest refraction spherical equivalent assessments at both Month 1 and Month 3 for this outcome assessment.
Percentage of eyes with a change of ≤ 1.00 Diopter in manifest refraction spherical equivalent (MRSE) between postoperative refractions, performed at 1 months and 3 months after surgery. Manifest refractions (eyeglass prescriptions) have three components: sphere, cylinder, and axis. Sphere and cylinder are both expressed in diopters, which is a continuous measure of the focusing power needed to make the image sharp on the retina.

SECONDARY outcome
Timeframe: 24 monthsPopulation: The number of eyes available for uncorrected visual acuity assessment at 12 months and 24 months were included in the analysis.
Percentage of eyes with loss of best spectacle corrected visual acuity (BSCVA) of \>2 lines. Mean change in best-corrected high contrast distance visual acuity. Corrected means spectacle corrected. Visual acuity (VA) was reported as letters read correctly, and the letters read were converted to logarithm of the minimum angle of resolution (logMAR) acuity. The participant read rows of letters on a standard LogMAR chart until the participant misses 3 letters on a row with 5 letters. The total number of correct letters were recorded. A decrease in the number of correct letters indicates a decrease in visual acuity. Acuity was averaged across visits.
