A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, EarlyView.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Fractional Klein-Gordon equation for linear dispersive phenomena: analytical methods and applications

, 2014
In this paper we discuss some exact results related to the fractional Klein--Gordon equation involving fractional powers of the D'Alembert operator. By means of a space-time transformation, we reduce the fractional Klein--Gordon equation to a fractional ...

Fluctuations in angle lambda with the pupil diameter and correlations with biometric values in a healthy population

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose Angle lambda (λ) is defined as the angle between the line of sight and the pupillary axis at the entrance pupil. We previously developed a child‐friendly and portable method to measure this angle in daily practice. In a given population, angle λ fluctuates according to age or refractive error.

Comparison of Surgically-induced Astigmatism using Topography and Keratometry in Patients undergoing Phacoemulsification and Small Incision Cataract Surgery: A Prospective Interventional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Topographic measurement of corneal astigmatism is the current standard of care because, in addition to measuring corneal astigmatism, it identifies irregular astigmatism, which may limit optimum surgical results.

Reviewing the benefits and clinical outcomes of oral fibroblasts over mesenchymal stem cells for repairing periodontal defects during or after orthodontic tooth movement

Periodontology 2000, EarlyView.
Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's
