Purpose
There has been a rapid expansion in the development and availability of premium intraocular lenses (IOLs) over the last two decades, with different lens types each having with their own benefits and drawbacks. This survey of UK refractive surgery consultants aimed to explore their IOL preferences, and the reasons for this.
Setting
An online survey was distributed to refractive surgery consultants across the UK, who practice cataract surgery, refractive lens exchange (RLE), and laser refractive surgery.
Methods
Respondents with two or less years of experience were excluded from the results. Questions aimed to elicit their preferred IOL for a typical cataract surgery (and the reasons for this) and a typical RLE (and their reasons for this). Other questions revolved around their thoughts on implementing mini-monovision when using extended depth of focus (EDoF) lenses and ‘mix-and-matching’ multifocal lenses with another IOL type (e.g. monofocal). Finally, they were asked at what level of corneal astigmatism would they prefer the use of a toric IOL. Responses were analysed for any trends.
Results
Thirty responses were analysed; mean years of refractive surgery experience was 12.8. The most popular IOL choices for cataract surgery (and the most cited reason for preference) were EDoF lenses (30%, better overall visual outcomes), monofocals (20%, fewer unwanted symptoms), and trifocals (20%, best spectacle independence). For RLE, EDoF remained most popular (36.7%), followed by trifocals (30%), and multifocals (16.7%).
Mini-monovision with EDoF lenses was well-regarded (83% recommend for most/select patients), unlike utilising IOL mix-and-match (60% did not recommend). 70% of respondents reported a corneal astigmatism threshold <1.25D for toric IOL use.
Conclusions
Experienced UK refractive surgeons prefer newer IOLs with enhanced optics; ≥50% favoured EDoF or trifocal IOLs. Notably, 70% opt for toric lenses at <1.25D of astigmatism. Mini-monovision with EDoF IOLs was well-regarded, whilst mix-and-match of different IOL types was less recommended.
