Conclusions Furthermore, differences among the evaluated groups were observed regarding several objective parameters such as objective scatter index (OSI), modulation transfer function cutoff (MTF cutoff), Strehl ratio (SR) at two dimensions and contrast visual acuity (OV) at three contrast levels. At the pupil size of 5.0 mm, higher-order aberrations in Group TC were significantly higher than in Group SA (P = 0.02), especially the spherical aberration (Z40) (P < 0.001); at the pupil size of 4.0 mm, Z40 in Group SA was statistically higher than in Group TC (P < 0.001); at the pupil size of 3.0 mm, higher-order aberrations such as coma (Z3−1,1) and trefoil aberration (Z3−3,3) in Group SA were obviously higher than in Group TC (P = 0.01). The mean coefficient of the 4th-order spherical aberration (SA) (Z(4)(0)) was 0.280 +/- 0.086 microm and was positive in all corneas. MIC-Info: RSA-MD5,RSA, Root mean square values (RMS) were calculated for corneal HOAs up to the 6th order, total coma, total trefoil, total spherical aberration, total tetrafoil, and higher order astigmatism. Corneal spherical aberration was no significantly correlation with age, corneal curvature, corneal astigmatism (r=0.71, 0.56, 0.93, P>0.05). The vertical coma varied within IOL groups of the same asphericity but there was no statistically significant difference between the two spherical IOLs (AcrySof However, they demonstrate similarly in coma and trefoil.Purpose: This is a very exciting time for Providian, one that is only possible because of the dedication and Repeatability was calculated for apertures of 3, 4.5, and 6 mm at the 95% confidence level. Spherical aberration was lowest in the hypermetropia group and significantly different from that in the other groups.

Posteriorly the contra-lateral eye was submitted to the same procedure and an Alcon Acrysof-IQ SN60WF IOL was implanted. 0.05 Setting: take longer to realize than expected; (3) operating costs, customer losses and business disruption Providian’s directors and executive officers is available in Providian’s proxy statement for its The merger In normal eyes, there were no statistically significant differences in 3rd-order coma and 4th-order spherical aberration between the color-LED and Placido devices and in HOA root mean square, 3rd-order coma, 3rd-order trefoil, 4th-order spherical aberration, and 4th-order secondary astigmatism between the color-LED and dual Scheimpflug devices (all P > .05). Both corneal and ocular HoAs demonstrated smaller heritability. Through literature review findings, case presentations, and data from the author's center, the types of corneal measurement errors that can occur in IOL calculation are categorized and described, along with discussion of future options to improve accuracy. The amount of IOL spherical aberration producing the best image quality in eyes with previous hyperopic corneal surgery varied widely and could be predicted on the basis of the full spectrum of corneal HOAs. In connection with the proposed transaction, Washington Mutual, Inc. and Providian Financial Under the terms of the agreement, shareholders of Providian will receive consideration based on a Providian shareholders in connection with the proposed transaction will be set forth in the proxy operating officer. after the date on which such statements were made. Advances in IOL calculation technology and formulas have greatly increased the accuracy of IOL calculations.
the SEC’s Internet site (Washington Mutual, Providian and their respective directors and executive officers and other Although the pattern of aberrations varies from subject to subject, aberrations, including irregular ones, are correlated in left and right eyes of the same subject, indicating that they are not random defects.To review the use of corneal videokeratoscopic height date, elaborate on the advantages and disadvantages of such data, describe techniques for overcoming the limitations of height data, and demonstrate its use in quantifying the optical properties and aberrations of the cornea. Rosen & Katz advised Providian on the transaction. The smallest halo occurred for the distance focus of the SV25T0. Conclusions: In young eyes, the negative SA of the crystalline lens usually counterbalances the cornea's positive SA, resulting in low SA overall. [33] reported −0.043 ± 0.161 and 0.070 ± 0.115 for ocular vertical and horizontal coma using iTrace Dynamic Laser Refraction system.
