“…Considering that treatment with alpha-1A adrenergic antagonist had no association with myopic shift, it is plausible that a pin-hole effect (increased depth of focus) due to constricted pupil size resulted in improved near vision instead of ciliary muscle contraction. Also, the small pupil provides partial tolerance to residual astigmatism, which led to improved image quality without decreasing stereoacuity and contrast sensitivity [26].…”

The objective of this study was to investigate the change in near visual function after the administration of oral silodosin to patients with lower urinary tract symptom (LUTS).Methods: This prospective study included treatment naï ve patients who were scheduled to start treatment with silodosin for LUTS. A comprehensive ophthalmological evaluation including the near vision and the automated pupillometry was performed at baseline and after 3 months of silodosin treatment. For subjective assessment of near visual ability and satisfaction, a Near Activity Visual Questionnaire-10 (NAVQ-10) was also used at the same time (higher scores indicating worse quality).Results: Of 23 patients enrolled in this study, 15 continued with silodosin (8 mg once daily) treatment for 3 months and completed a follow-up evaluation. The mean age of participants was 60.4±8.4 years. Distant visual acuity and spherical error were unchanged after silodosin treatment. However, near vision acuity (logMAR) was improved after treatment (

“…Most likely, it will take years of clinical studies to learn how to interpret this new information, associate it with different pathologies or conditions, and determine whether it has a real clinical application or is just a curiosity. The applications of ocular aberrometry are ubiquitous: they include refractive surgery (i.e., LASIK) 28 , the diagnosis and monitoring of diseases 29 , myopia control 30 , intraocular lenses 31 , light-adjustable intraocular lenses 32 , objective refraction 33 , intraoperative aberrometry 34 , and vision science 35 . Additionally, combining a wavefront sensor with a compensating element, such as a liquid crystal spatial light modulator, has dramatically improved in vivo observations of the human retina 36 .…”

Ocular optics is normally estimated based on up to 2,600 measurement points within the pupil of the eye, which implies a lateral resolution of approximately 175 µm for a 9 mm pupil diameter. This is because information below this resolution is not thought to be relevant or even possible to obtain with current measurement systems. In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 µm, which implies roughly 1 million measurement points for a pupil diameter of 9 mm. The results suggest that the normal human eye presents a series of hitherto unknown optical patterns with amplitudes between 200 and 300 nm and is made up of a series of in-phase peaks and valleys. If the results are analysed at only high lateral frequencies, the human eye is also found to contain a whole range of new information. This discovery could have a great impact on the way we understand some fundamental mechanisms of human vision and could be of outstanding utility in certain fields of ophthalmology.
