News Update on Cataract Surgery Research: Dec – 2019

Femtosecond laser–assisted cataract surgery

Femtosecond laser–assisted cataract surgery affords surgeons an interesting new option to probably improve patient outcomes and protection. Over the past 2 years, four precise laser systems have been delivered into the marketplace. The creation of this new generation has been followed by a host of recent medical, logistical, and monetary challenges for surgeons. This article describes the evolution of femtosecond laser generation for use in cataract surgical operation. It opinions the to be had laser systems and discusses the essential adjustments in cataract surgical procedure technique and the logistics of incorporating a femtosecond laser into one’s practice.

The Value of Routine Preoperative Medical Testing before Cataract Surgery

BACKGROUND: Routine preoperative clinical checking out is normally done in patients scheduled to undergo cataract surgical procedure, even though the cost of such checking out is uncertain. We completed a study to determine whether routine checking out enables reduce the occurrence of intraoperative and postoperative medical headaches.

METHODS: We randomly assigned 19,557 non-obligatory cataract operations in 18,189 sufferers at 9 facilities to be preceded or no longer preceded by means of a general battery of clinical checks (electrocardiography, entire blood remember, and dimension of serum levels of electrolytes, urea nitrogen, creatinine, and glucose), further to a records taking and physical examination. Adverse clinical occasions and interventions at the day of surgery and during the seven days after surgical treatment have been recorded. [2]

Acute Endophthalmitis Following Cataract Surgery: A Systematic Review of the Literature

Objectives  To determine the mentioned prevalence of acute endophthalmitis following cataract extraction through the years and to explore viable contributing elements, which include type of cataract incision.

Methods  A systematic review of English-language articles turned into carried out via appearing a vast search of PubMed from 1963 through March 2003 the use of such terms as cataract extraction, endophthalmitis, and postoperative hardship. Additional research had been diagnosed from bibliographies of relevant articles and posted proceedings. Surgical approach became recorded, while available. Pooled incidence prices and relative dangers of growing endophthalmitis using specific incision strategies have been assessed. [3]

Phacoemulsification Cataract Surgery Affects the Discriminative Capacity of Iris Pattern Recognition

Cataract is a commonplace ophthalmic disease and the main cause of blindness worldwide. While cataract is cured via surgical strategies, its effect on iris based totally biometric recognition has no longer been correctly studied. The key objective of this research is to assess the effect of cataract surgical procedure on the iris texture pattern as a method of personal authentication. We prepare and release the IIITD Cataract Surgery Database (CaSD) captured from 132 cataract sufferers using 3 commercial iris sensors. A non-comparative non-randomized cohort take a look at is completed on the iris texture patterns in CaSD and authentication overall performance is studied the usage of 3 biometric popularity systems.

The Effect of Cataract Surgery on the Intraocular Pressure in Eyes with and without Pseudoexfoliation Syndrome

Aims: To decide the impact of cataract surgery on the intraocular pressure (IOP) in eyes with and with out pseudoexfoliation syndrome (PXF).

Study Design:  prospective, non-randomized, age-matched managed, medical observe.

Place and Duration of Study: Department of Ophthalmology, Assiut University Hospital, Assiut; Egypt, among January 2015 to December 2016.

Methodology: This have a look at included two groups of non-glaucomatous eyes with visually full-size senile cataract:  32 eyes with PXF (PXF organization), 32 eyes with out PXF (manipulate group).  In every group, planned extracapsular cataract extraction (PECCE) changed into finished in 22 eyes and phacoemulsification become executed in 10 eyes. IOP turned into measured at one week, one month and three months postoperatively and compared to the preoperative values. [5]
