Microdroplet and splatter contamination during phacoemulsification in COVID-19 era

Half a millilitre of fluorescein was incorporated into 400ml of balanced salt solution to identify microdroplet and splatter from phacoemulsification to simulate possible COVID-19 contamination. Five porcine eyes were mounted to an ophthalmic mannequin head and two surgeons (height 189cm,...

Biometric changes in phakic eyes over time

This was a single-centre retrospective cohort study of patients who attended a ‘two-stop’ preassessment clinic for consideration of cataract surgery between November 2002 and March 2015. Four biometric measurements were recorded: axial length, horizontal (K1) readings, vertical (K2) readings and...

Risk stratification to reduce intraoperative cataract surgical complications

The authors prospectively collected data on 1135 consecutive patients undergoing cataract surgery. They were risk stratified according to categories – A (no additional risk factors, 0 points), B (vitrectomy, corneal scarring, small pupil less than 3mm, shallow anterior chamber less...

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

Are corneal guttata an additional risk factor in complicated cataract surgery needing a future corneal transplant?

This registry-based cohort study from Sweden utilised data from the Swedish National Cataract Registry and the Swedish Cornea Transplant Registry. Patients who underwent phacoemulsification with a posterior intraocular lens between 2010 and 2012 numbered 192,476. Of these cases, 288 underwent...

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

Suture-less flanged IOL fixation vs. conventional sutured SF in IOL dislocation

The authors report the analysis of a prospective, comparative cohort study on 103 consecutive patients (103 eyes) with intraocular lens (IOL) dislocation who underwent vitrectomy with IOL removal and sutured scleral fixation (SF) (53 eyes) or flanged IOL fixation (50...

Wet AMD outcomes post cataract surgery

The authors present the findings of a retrospective study looking at the progression of wet age-related macular degeneration (AMD) in patients who underwent cataract surgery. They recruited a series of 111 patients of which 38 were men and 73 were...

Oral glycerol effect on anterior chamber depth during cataract surgery

The authors present the findings of a controlled clinical trial where cataract patients having surgery for both eyes at least seven days apart were given oral glycerol preoperatively when operating on the right eye. This meant that the left eye...

Can the angle of origin of the ophthalmic artery predict embolic trajectory?

A retrospective, comparative case-control study was used to test the hypothesis that a risk factor for retinal versus cerebral infarct is the angular origin of the ophthalmic artery from the internal carotid artery. The study compared one group (n=28) who...

Thalamic infarcts and the associated neuro-ophthalmic sequelae

The authors present a retrospective review of clinical and imaging data from a stroke database over a 10-year period. Of those identified as having a thalamic infarction (n=342), 40 were found to have neuro-ophthalmic sequelae (11.7%). The neuro-ophthalmic sequelae reported...

Large series profiling skew deviation

A retrospective notes review was completed for patients identified as having skew deviation. The authors outline their exact definition of skew deviation within the methods of the paper. One hundred and fifty-seven patients were identified, it is not clear over...
