Review of current status of refractive lens exchange and role of dysfunctional lens index as its new indication.

Indian J Ophthalmol 2020 Dec;68(12):2797-2803

Department of Cataract and Refractive Surgery, Narayana Nethralaya, Bengaluru, Karnataka, India.

Advances in phacodynamics and intraocular lenses (IOLs) has given second life to clear lens extraction (CLE) or refractive lens exchange (RLE) in recent years for the treatment of patients with high degrees of myopia, hyperopia, and astigmatism who are unsuitable for laser surgery. Furthermore, presbyopia treatment with RLE supplemented with multifocal or accommodating IOLs gives the dual benefit of correcting refractive errors with eliminating the need for cataract surgery. RLE should be consistent and effective for a good refractive outcome along with safety during the surgical procedure and in the postoperative period. Read More

Visual quality observation of clear lens extraction by ultrasonic phacoemulsification and intraocular lens implantation in a child with microspherophakia: A case report.

Medicine (Baltimore) 2020 Aug;99(34):e21937

Cataract Department, Shanxi Eye Hospital, Taiyuan, Shanxi Province, China.

Rationale: Microspherophakia is characterized by a small, spherical crystalline lens with increased sagittal diameter. Because of the uncertainty about the outcome, as well as the complexity of the operation and development of complications, the management and timing of surgical intervention for microspherophakia are still debated. Lens extraction is effective for avoiding the risk of pupillary blockage, but the outcome after operation is controversial. Read More

[Rhegmatogenous retinal detachment : Epidemiology and risk factors].

Ophthalmologe 2018 02;115(2):163-178

Univ.-Klinik für Augenheilkunde und Optometrie, Medizinische Universität Innsbruck, Anichstr. 35, 6020, Innsbruck, Österreich.

The incidence of rhegmatogenous retinal detachment in the European population is approximately 10 cases per 100,000 inhabitants per year and reaches a peak in the 6th and 7th decades of life, mostly in atemporal association with posterior vitreous body detachment. Known risk factors include myopia and higher axial length of the eye, male gender, previous trauma and vitreoretinal degeneration or dystrophy. In recent years, an increase in the risk of rhegmatogenous retinal detachment following cataract surgery was also found, especially after capsule rupture and vitreous body loss. Read More

Mini-review: Far peripheral vision.

Vision Res 2017 11 11;140:96-105. Epub 2017 Sep 11.

Simpson Optics LLC, 3004 Waterway Court, Arlington, TX 76012, United States. Electronic address:

The region of far peripheral vision, beyond 60 degrees of visual angle, is important to the evaluation of peripheral dark shadows (negative dysphotopsia) seen by some intraocular lens (IOL) patients. Theoretical calculations show that the limited diameter of an IOL affects ray paths at large angles, leading to a dimming of the main image for small pupils, and to peripheral illumination by light bypassing the IOL for larger pupils. These effects are rarely bothersome, and cataract surgery is highly successful, but there is a need to improve the characterization of far peripheral vision, for both pseudophakic and phakic eyes.

Refractive lens exchange.

Surv Ophthalmol 2014 Nov-Dec;59(6):579-98. Epub 2014 May 9.

Clinical Department of Ophthalmology, Silesian University of Medicine, SPSK nr 5, Katowice, Poland; Technical University of Czestochowa, Institute of Physics, Faculty of Materials Processing Technology and Applied Physics, Czestochowa, Poland.

Advances in small incision surgery have enabled cataract surgery to evolve from being concerned primarily with the safe removal of the opaque crystalline lens to a procedure refined to yield the best possible postoperative refractive result. As the outcomes of cataract surgery have improved, the use of lens surgery as a refractive modality in patients without cataracts (clear lens extraction) has increased in popularity. The removal of the crystalline lens for refractive purposes, or so-called refractive lens exchange (RLE), offers distinct advantages over corneal refractive surgery in selected cases. Read More

Prevalence of myopic shifts among patients seeking cataract surgery.

Medicina (B Aires) 2013 ;73(3):207-12

Departamento de Oftalmología, Centro Médico San Luis, Buenos Aires, Argentina.

Modern cataract surgery by phacoemulsification is a widely accepted procedure with a rapid recovery time. The prescription of specific intraocular lens, implanted during surgery, makes it possible to anticipate whether the patient will need reading glasses after the procedure. The present study analyses a sample of cataract surgery patients to show the frequency of myopic shifts related to nuclear opacity, which can result in clear near vision before surgery. Read More
