A retinoscopic survey of 333 horses and ponies in the UK [PDF]
, 2014 Introduction: Ophthalmic examination in the horse is generally limited to crude assessment of vision and screening for ocular lesions. The refractive state of equine eyes and the potential impact on vision and performance requires further ...

Eye shape and retinal shape, and their relation to peripheral refraction [PDF]
, 2012 Purpose: We provide an account of the relationships between eye shape, retinal shape and peripheral refraction. Recent findings: We discuss how eye and retinal shapes may be described as conicoids, and we describe an axis and section reference system for

Photorefractive keratectomy for compound myopic astigmatism
American Journal of Ophthalmology, 2000 To evaluate the safety and efficacy of photorefractive keratectomy for the treatment of primary compound myopic astigmatism.In a prospective study, 93 eyes from 56 patients with a mean spherical equivalent of -4.98 +/- 1.80 diopters (range, -1.75 to -8.5) underwent photoastigmatic refractive keratectomy with the Summit Apex Plus excimer laser using ...

LASIK for spherical refractive myopia: effect of topographic astigmatism (ocular residual astigmatism, ORA) on refractive outcome. [PDF]
PLoS ONE, 2015 In eyes with a preoperative plano refractive cylinder, it would appear that there is no rationale for astigmatic treatment. The aim of this retrospective, cross-sectional data analysis was to determine the amount of topographic astigmatism in refractive ...
