Abstract

A new variable power cross-cylinder lens set is described. It differs from the well known Stokes variable power cross-cylinder lens set, which is made of cylinder lenses of equal but opposite power, in that in the new variable power cross-cylinder lens set both lens elements are identical. These elements can be sphero cylindrical of any type and can be designed to give the same effect as a Stokes lens set or create a spherical bias or offset of a desired amount. The action of this lens set is analyzed using 3-dimensional refractive space.

Study of corneal topographic patterns with single continuous suturing techniques in penetrating keratoplasty.

PURPOSE: To study the corneal topographic patterns following three different types of single continuous suturing techniques in penetrating keratoplasty. METHODS: One hundred forty-eight maps obtained from 40 patients who underwent penetrating keratoplasty with single continuous suturing were retrospectively analyzed at a tertiary eye care center. The videokeratograph maps were obtained on the Eye Sys System 2000 at 1, 3, and 6 months after surgery. Suture adjustment was done for cases with astigmatism greater than 3 diopters, and maps were also obtained after suture adjustment. The maps were classified according to the corneal profile and the astigmatic pattern seen in the topographic maps. RESULTS: Combined prolate patterns were seen most frequently, and their proportion was significantly higher at 1 month ( p= 0.009), 3 months ( p= 0.0004), and 6 months ( p= 0.0008). The simulated keratometric astigmatism was significantly higher in the prolate group compared with the other groups at 1 month ( p= 0.0021). However, all the topographic patterns showed comparable magnitude of astigmatism after suture adjustment and at 3 and 6 months. The antitorque suturing technique showed a higher proportion of prolate maps compared with the other suturing techniques. CONCLUSIONS: Prolate patterns of the cornea are the most frequently seen patterns after single continuous suturing, which is the normal physiological pattern of the cornea. The initial astigmatism is higher in the prolate pattern, which can be successfully reduced with suture adjustment.

Treating astigmatism at the time of cataract surgery.

An increasingly important goal of modern cataract and implant surgery is to obtain the most desirable refractive outcome for our patients, and in so doing, decrease their dependence upon spectacle correction. Refined spherical outcomes are now achieved by directing close attention to biometry technique, through the use of third generation intraocular lens (IOL) power formulae, and refinements in technology such as partial coherence interferometry. Similarly, improvements in astigmatic outcomes are now possible by focusing upon and obtaining more accurate preoperative cylinder measurements, careful surgical planning particularly in regard to incision(s) design, use of toric IOLs, and employing advanced postoperative enhancement techniques. Because of these refinements in technique and technology, the field of cataract and implant surgery has emerged as a true and recognized form of refractive surgery.

Comparison of exact pupil astigmatism conditions with Seidel approximations.

The aberrations of axisymmetric imaging systems can be calculated to third order by use of the Seidel formula. The Coddington equations give aberrations that have quadratic dependence on the pupil, for all field points. The pupil astigmatism conditions were recently developed to predict and control aberrations that have quadratic field dependence and arbitrary pupil dependence. We investigate the relationship between the exact pupil astigmatism conditions and the classical Seidel treatment of pupil aberration.
