Considerations on the Haigis formula: Are better outcomes possible with tuning?

Acta Ophthalmologica, EarlyView.
Abstract Purpose To design a vergence‐based lens power formula based on the classical Haigis formula for better outcomes while retaining the original formula architecture. Methods Four new formula variants (A–D) incorporating a sum of segments correction for axial length, harmonic mean of corneal radii instead of arithmetic mean (all variants), and ...

Fundus autofluorescence lifetimes in age‐related macular degeneration versus healthy controls in a pseudophakic population

Acta Ophthalmologica, EarlyView.
Abstract Purpose To check whether prolonged fundus autofluorescence (FAF) lifetimes in age‐related macular degeneration (AMD) could be an artefact resulting from lens fluorescence. Methods Fluorescence lifetime imaging ophthalmoscopy (FLIO) was performed in pseudophakic intermediate AMD as well as healthy controls. The median values of FAF lifetimes in

Presbyopia Correction in Lens Replacement Surgery: A Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review

Corneal characteristics in children with Marfan syndrome with or without ectopia lentis

Pediatric Investigation, Volume 9, Issue 2, Page 160-166, June 2025.
Children with Marfan Syndrome who have dislocation of the natural lens of the eye also have abnormalities of eye shape and size. These abnormalities are not apparent in Marfan's children who do not have lens dislocation, implying that the children with lens dislocation have a more severe genetic defect of fibrillin proteins.

Bilateral Toric Phakic Intraocular Lens Implantation for Correction of High Myopic Astigmatism in a Patient with Marfan Syndrome with Lens Coloboma: A Case Report

Case Reports in Ophthalmology, 2021
Marfan syndrome (MFS) is known to cause significant refractive error. Treatment options are limited in this condition for correcting refractive error. Clear lens exchange is done in these cases, but complication rates are high.
