Abstract

Purpose: To study the agreement between manifest refraction (Rx) and objective refraction (ObjRx) measured with two autorefractor models and an aberrometer, in eyes implanted with a trifocal diffractive intraocular lens. Setting: IOA Madrid Innova Ocular, Madrid, Spain. Design: Prospective comparative cohort study. Methods: A Topcon KR8800 autorefractor, based on a Scheiner double-pinhole, and a NIDEK OPD-SCAN III aberrometer, based on the scanning-slit retinoscopy principle, were used to obtain objective refraction (ObjRx) readings. In addition, lower-order Zernike coefficients (Z) were used to calculate ObjRx. A set of 7 different results in power vector notation [M(spherical equivalent), J0 and J45] for 7 different methods was obtained: Rx, AR (automated refraction obtained with the KR8800), WF-P (Z-based ObjRx for the photopic pupil), WF-M (Z-based ObjRx for the mesopic pupil), WF-4 (Z-based ObjRx for a 4 mm pupil), OPD-C (automated refraction measured with the OPD under photopic conditions), and OPD-M (automated refraction measured with the OPD under mesopic conditions). Results: The study comprised 102 eyes from 51 cataract patients who underwent binocular implantation of the POD F IOL. All 6 objective methods yielded more negative M values than manifest refraction (Rx) (p < 0.001). As for the astigmatism components (J0 and J45), only AR (p = 0.003) and OPD-M (p < 0.001) differed significantly from Rx. The best and worst correlation for the M component were ICC=0.70 (for WF-M) and ICC=0.48 (WF-4). Conclusions: Objective methods tend to yield more negative sphere values than manifest refraction.

Abstract

To review binocular and accommodative disorders documented after corneal or intraocular refractive surgery, in normal healthy prepresbyopic patients. A bibliographic revision was performed; it included works published before 1st July 2017 where accommodation and/or binocularity was assessed following any type of refractive surgical procedure. The search in Pubmed yielded 1273 papers, 95 of which fulfilled the inclusion criteria. Few publications reporting binocular vision and/or accommodative changes after refractive surgery in normal subjects were found. The reduction in fusional vergence is the most frequently reported alteration. Anisometropia is an important risk factor for postoperative binocular vision‐related complaints. Most diplopia‐related visual complaints, irrespective of the surgical procedure, were in fact misdiagnosed preoperative disorders. The preoperative evaluation of patients seeking spectacle/contact lens independence should include a complete binocular and accommodation assessment where parameters such as the phoric posture, accommodative amplitude and facility, near point of convergence, fusional reserves and accommodative convergence/accommodation coefficient are measured. This would allow the identification of risk factors that could compromise the success of the refractive surgery and cause clinical symptoms. [ABSTRACT FROM AUTHOR]
