Incidence and risk factors of late in the bag intraocular lens dislocation

The aim of this study was to identify risk factors for late in the bag dislocation over a 21 year period. Worldwide the incidence varies from 0.05% to 3.0%. In this Swedish study they report an increase in incidence in...

Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....

From monofocal to premium: Understanding the expanding landscape of intraocular lenses

For many years cataract surgery was framed almost entirely as a restorative procedure. The goal was straightforward: remove the cloudy lens and replace it with a clear one, restoring distance vision and allowing the patient to function comfortably with reading...

Effect of caffeine and low intensity endurance exercise on intraocular pressure

This placebo controlled, double blind, balanced crossover study reports in healthy individuals that 30 minutes of cycling caused a maximum of 2.7mmHg lowering of IOP. A caffeine dose of 4mg/kg 30 minutes prior to cycling negated this effect. The conclusion...

The rate of realignment of two toric monofocal intraocular lenses (IOL)

This retrospective study used the American Academy of Ophthalmology Registry data to analyse the need of reoperation for realignment within the first year after cataract surgery with a TECNIS or AcrySof monofocal toric IOL implanted during 2016 and 2017. They...

Intraocular surgery and dry eye: Understanding the link, minimising the risk and preparing for the future

Dry eye disease (DED) and ocular surface disease (OSD) are increasingly recognised as central factors in contemporary intraocular surgery. As cataract, glaucoma and vitreoretinal procedures advance toward greater refractive precision, patient expectations have risen and tolerance for postoperative visual fluctuation...

Multicentre PCO rates in different brands of monofocal intraocular lenses

This was a longitudinal, retrospective cohort study featuring 47,754 (three years) and 20,763 (five years) eyes with age-related (≥65 year) cataract surgeries between 2010-2013 across seven UK ophthalmology clinics. The three- and five-year incidence of posterior capsular opacification (PCO) and...

Does religious fasting affect intraocular pressure or retinal parameters?

Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...

An unusual case of silicone oil in the anterior chamber simulating intraocular implant

Silicone oil internal tamponade has been used for over 50 years, even prior to pars plana vitrectomy [1].Over a course of time silicone oil may migrate to the anterior chamber through the pupil. This may disperse in the form of...

Influence of capsular tension ring implantation on rotational stability of intraocular lenses

This is a systematic review and meta-analysis aiming to determine the effect of capsular tension ring (CTR) placement on intraocular lens (IOL) rotational stability. Twelve studies (1251 eyes; 639 CTR, 612 non-CTR) were included from literature search of PubMed, EMBASE,...

Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...
