Ocular surface characteristics and its association with soft contact lens fitting

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 7, Page 1715-1728, November 2025.
Abstract Purpose To analyse the associations between ocular surface shape parameters and soft contact lens fitting. Methods A total of 106 eyes of 53 participants (53 right and 53 left eyes) fitted with standard silicone hydrogel soft lenses were analysed retrospectively.

Zulu ocular biometry differs fundamentally from that of Europeans – A modelling analysis

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 7, Page 1829-1836, November 2025.
Abstract Purpose The accuracy of ocular refraction calculations depends on reliable biometry and the validity of the models upon which the calculations are based. Most models are based on European eyes, so their validity in sub‐Saharan Africans may be questioned, potentially contributing to suboptimal postoperative outcomes. Hence, this study developed

Ophthalmomyiasis externa by Musca domestica in a case of orbital metastasis

open access: yesIndian Journal of Ophthalmology, 2013
Infestation of the living tissues of the eye, ocular adnexae or orbit by larvae of flies of the order Diptera is known as ophthalmomyiasis. Ophthalmomyiasis externa is a limited superficial infestation of external ocular structures such as conjunctiva ...

Reliability and repeatability of the Pentacam on corneal curvatures [PDF]

open access: yesClinical and Experimental Optometry, 2009
The purpose of this study was to assess the intra-observer reliability and inter-session repeatability of the Pentacam system (Oculus, Inc.) on the simulated keratometry readings (Sim K) and peripheral corneal curvatures (PCC) at both the anterior and posterior corneal surfaces.One eye was randomly selected from each of the 39 normal subjects from the ...

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

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 7, Page 1837-1844, November 2025.
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.
