Abstract
We compared preoperative and 1- and 3-month postoperative measurements of anterior and posterior corneal curvature, anterior and posterior corneal astigmatism, anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) width, central corneal thickness (CCT), and the co...

Abstract
To report the refractive results after LASIK for high myopia and cylinder at one center with one surgeon comparing two laser platforms.
A total of 206 eyes of 121 patients were treated for -6.00 to -12.00 diopters (D) of spherical equivalent refractive error with up to 3.00 D of cylinder. All eyes u...

Abstract
To examine the impact of pupil center location uncertainty in wavefront sensing on the variance in repeated measures of higher order root-mean-square (RMS) wavefront error (WFE).
Dilated WFE for one normal eye and one eye with keratoconus of two patients were measured using a custom Shack-Hartmann w...

Abstract
The results in this analysis might provide normative data for cataract patients and a useful reference for multiple purposes. The correlation of AL with corneal radius, ACD, and corneal diameter in normal eyes was not present in eyes with extreme myopia or hyperopia.

Abstract
The study enrolled 107 patients with a mean age of 69.9 years +/- 7.7 (SD). The image quality was sufficient for IOL rotation analysis in 91% of eyes. The mean rotation between the first day postoperatively and 120 to 180 days was 1.93 +/- 2.33 degrees, with 96% of IOLs rotating fewer than 5 degrees...

Abstract
The precision of the PCI measurements was extremely high for AL with low fluctuations (95% limits of agreement [LoA], 0.06 mm) and was relatively high for K readings with higher fluctuations (95% LoA, 0.55 D) and for ACD (95% LoA, 0.2 mm). The precision of astigmatism and cylinder axis was high in f...

Refractive error data are presented for a population base that has not been previously reported, although Polish Americans comprise 3% of the US population. Myopia is more common in young Polish patients than in the general US population. The strong hyperopic shift in older patients may either be no...

Abstract
Toric error was reduced in each of the patients and refractions remained stable for the 9 month follow-up period. Achieved spherical equivalent manifest refraction (MRSE) was within 0.25 D of targeted emmetropia. All five patients improved their UCVA to >or=20/25 (

Abstract
There were age-related shifts toward against-the-rule and with-the-rule astigmatisms for the anterior and posterior corneal surfaces, respectively. The compensating effects of the posterior corneal surface on anterior corneal astigmatism decreased with advancing age....

Abstract
DLEK provides good visual acuity (> or =20/40) for the majority of patients at 1 year with stable refractive error compared with baseline. Refractive stability was observed with both large- and small-incision DLEKs; however, worrisome endothelial cell loss was observed, especially with a small-incis...

Abstract
IntraLase-enabled astigmatic keratotomy is an effective treatment for high astigmatism after penetrating keratoplasty with an encouraging refractive predictability. Future studies may help refine the treatment parameters required to achieve reduction of cylinder with greater accuracy.

Abstract
From those recruited, 15.2% were hypermetropic; 11.1% were myopic; and 6.2% had astigmatism. Participants became progressively more hypermetropic with increasing age until the age of 70 years, after which time they become more myopic. Furthermore, there was an increasing likelihood of myopia and a d...

Abstract
Even in the youngest age group, astigmats tested with astigmatism correction showed reduced acuity for both V and H gratings, which suggests that astigmatism is having a negative influence on visual development. We found no evidence of orientation-related differences in astigmatism-corrected grating...

Abstract
Corneal biomechanical properties measured by corneal hysteresis and corneal resistance factor were decreased at 10 days after LASIK. Minimal recovery (approximately 10% of the changes) was achieved by 3 months. The changes in biomechanical properties may affect IOP measurement.

Astigmatism is common in Taiwanese preschool children. The predominant types are with-the-rule and oblique astigmatism. Most patients with high astigmatism and high corneal astigmatism have with-the-rule type. High BMI or weight is associated with with-the-rule astigmatism and with with-the-rule cor...
