AC/A non-linearity

This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...

Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Age versus heterophoria and fusional vergence measures

This study aimed to establish the relationship between age, horizontal heterophoria, horizontal vergences, positive / negative fusional vergence and vergence facilities. The study recruited 112 subjects aged 39.8 ±14.97 years (range 18-65) of which 54.5% were female. There were 49...

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...
