Advances in the design and performance of intraocular lenses (IOLs) continue to be driven by demand for better outcomes, presbyopia correction and spectacle independence, alongside a better understanding of the dynamics of the crystalline lens, newer theories of accommodation and...
In the next instalment of this series I focus on problems associated with biometry and intraocular lens (IOL) selection for cataract surgery. I have taken previous medicolegal cases I have dealt with and tried to extract some learning points and...
Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...
The authors aimed to evaluate the effect of age at primary intraocular lens (IOL) implantation on the rate of refractive growth during childhood. This was a retrospective study of 296 eyes of 219 patients. Forty-six met inclusion criteria; 28 unilateral...
The optical performance of pseudophakic eyes were compared after implantation of spherical and aspheric IOLs in paediatric patients after cataract surgery. This randomised controlled trial included 40 eyes of 23 patients: 20 eyes in each group. Follow-up was over three...
In this retrospective study, the authors examined 31 eyes of 20 patients who had received a supplementary trifocal sulcus IOL in addition to a ‘bag-in-the-lens’ IOL. Implantation of a ‘bag-in-the-lens’ IOL requires the creation of anterior and posterior capsulotomies, followed...
The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...
Multifocal IOLs (MIOLs) keep evolving to try and get the best outcome in terms of vision and reduction of side-effects. This prospective interventional study was carried out on 34 eyes of 17 patients (11 women (65%) and six men (35%))...
The purpose of this study was to present the long-term outcome of IOLs in paediatric patients who received cataract surgery aged seven to <24 months. This was retrospective study with minimum follow-up of 12 months for 27 patients (28 eyes)....
The authors evaluate 50 eyes of 28 patients that underwent an angle fixated phakic intraocular lens (IOL) implantation (Acrysof Cachet). All eyes had moderate to high myopia (-5.25 to-19.63 dioptres) and IOL sizing was performed as per the manufacturer’s recommendation....
In this study the authors made a comparison of significant postoperative tilt of IOL with air tamponade as opposed to balanced salt solution, in the procedure of combined phaco with IOL and vitrectomy. Thirty-four patients were included into the analysis....
The purpose of this study was to present the long-term outcome of IOLs in paediatric patients who received cataract surgery aged seven to <24 months. This was retrospective study with minimum follow-up of 12 months for 27 patients (28 eyes)....
