Purpose l.jpg

Purpose

  • To quantify the severity of corneal astigmatism in patients awaiting cataract surgery in our local population.

  • To establish the demand and cost of a toric IOL service in our unit if used at different minimum levels of astigmatism (current  3D).


Methods l.jpg

Methods

  • A prospective study of patients attending preoperative assessment for cataract surgery in Singleton Eye Unit was completed between 04/01/09 and 05/31/09.

  • Keratometry measurements were recorded for all phakic eyes in dioptres using automated keratometry (IOL Master, Carl Keiss Meditec).

  • Exclusion criteria- known corneal disease, previous corneal or intraocular surgery, age less than 30 years.


Results l.jpg

Results

2 eyes (1 patient) excluded from further analysis

(undiagnosed keratoconus (K1/K2 37.71/53.66OD and 40.37/47.40OS))

Results

Reducing the astigmatism threshold for toric IOLs in our unit from 3D to 2.5D would result in additional IOL cost of £4859pa.

* Based on mean 2600 cases/year in Singleton Eye Unit.

**Rayner T-flex toric IOL £143.75/ IOL v Acrysof SA60T £69/IOL (Sep 2009).


Conclusions l.jpg

Conclusions

  • A lower prevalence of moderate/high corneal astigmatism was evident in our patient population compared to a previous large-scale multicentre study. The astigmatism threshold for toric IOLs in our unit could be reduced from 3D to 2.5D.

  • Our results suggest that the severity of corneal astigmatism may differ in different patient populations. The reasons for this are unclear. Our patient population is largely Caucasian, the role of ethnicity was not addressed and requires further research.

  • In a publicly-funded health system such as the National Health Service, local patient information is important in establishing local demand/costs for services such as toric IOLs.
