Purpose. To determine if spectacle corrected and uncorrected astigmats show reduced performance on visual motor and perceptual tasks. Methods. Third through 8th grade students were assigned to the low refractive error control group (astigmatism < 1.00 D, myopia < 0.75 D, hyperopia < 2.50 D, and anisometropia < 1.50 D) or bilateral astigmatism group (right and left eye ≥ 1.00 D) based on cyclopl...

OBJECTIVE To evaluate efficiency, predictability, stability, complications, and patient satisfaction after implantation of a foldable iris-fixated phakic intraocular lens (PIOL) for the correction of myopia. DESIGN Prospective, nonrandomized, comparative (self-controlled) trial. PARTICIPANTS Forty-one eyes of 22 myopic patients aged 18 to 56 years (mean, 36 years) with average sphere of -8....

PURPOSE To evaluate effectiveness, safety, predictability, and short-term stability of laser in situ keratomileusis (LASIK) using the LaserSight Compac-200 Mini excimer laser with software version 9.0, for all refractive errors. METHODS One hundred fifty consecutive patients (300 eyes) that received bilateral LASIK for myopia, hyperopia, and astigmatism were studied prospectively. A new 9.0 s...

PURPOSE To evaluate the efficacy and safety of neural vision enhancement technology (NVC, NeuroVision, Inc.) to improve visual acuity and contrast sensitivity function in eyes with low myopia. SETTING Singapore Eye Research Institute, Singapore, Singapore. METHODS This noncomparative interventional case series comprised 20 Asian adults between 19 and 53 years of age with low myopia (cyclopl...

OBJECTIVE To compare visual outcomes in eyes undergoing aberrometry-guided (InterWave) LASIK with those in eyes undergoing standard LASIK treatment based upon refractive measures. DESIGN Single-center, comparative, interventional, consecutive case series. PARTICIPANTS Four hundred two consecutive eyes undergoing LASIK were analyzed retrospectively. One group, 106 eyes undergoing primary LAS...

METHODS: In this consecutive case series, patients underwent phacoemulsification and bilateral or unilateral IOL implantation with the M-flex T IOL (Rayner Intraocular Lenses Ltd.). All underwent refractive assessment and corneal topography preoperatively and postoperatively. Outcome measures included uncorrected distance VA, spherical and cylindrical refraction, and spherical equivalent (SE) (...
