By Alois K. Dexl, MD, MSc Within the past few decades, various surgical procedures for the treatment of presbyopia have been implemented in cataract and refractive surgery. Recently introduced into the market was the Kamra corneal inlay (AcuFocus, Inc., Irvine, California). This inlay has the Conformité Europpeéne (CE) Mark and is currently commercially available in the European Union and other...

Background: Presbyopic Spectacles Correction Coverage (PSCC) is a measure of presbyopic spectacle utilization in defined area. Previous studies Africa and Asia have shown low Met Need high Unmet Presbyopia Needs with different barriers responsible for these. 
 Purpose: To determine the rate spectacles identify to Chikun LGA, Kaduna State, Nigeria.
 Materials Methods: One thousand fort...

The authors conducted a review of classical and conflicting theories of accommodation and presbyopia. They make a critical comparison with the findings of magnetic resonance imaging (MRI) that have been developed in recent decades. Based on these studies, formulates a new approach on the subject, shifting the focus of the discussion of the lens to the posterior pole of the eye.

This paper presents a study designed to compare optical quality expressed through PSF (Point Spread Function), MTF (Modulation Transfer Function) and OSI (OqasTM Scattering Index) between several intraocular implants for presbytia surgery. These are: TecnisTM ZM900, Acri.LISATM 366D, ReSTOR SN6AD1 and Crystalens® HD. Historically, research on the optical quality of intraocular lenses developed ...

purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...

Purpose: Investigate the prevalence of near vision impairment in older adults in a low-middle income urban area of São Paulo city, Brazil. Methods: Cluster sampling based on geographically-defined census sectors was used in randomly selecting individuals ≥50 years of age for visual acuity measurement for near and distance (tumble E logMAR chart), refraction, and slit-lamp examination during 200...
