PURPOSE: To assess the cost-effectiveness of the treatment of low corneal astigmatism (≤1.5 diopters) at the moment of cataract surgery.
SETTING: Qvision, Ophthalmology Department, VITHAS Almería Hospital, Spain.
DESIGN: Economic evaluation.
METHODS: A decision tree was used to assess the cost-effectiveness of implanting spherical vs toric intraocular lenses (IOLs) or spherical lens combined with the following corneal incisions: limbal-relaxing incisions conducted manually (M-LRI) or assisted by femtosecond laser (F-LRI), arcuate keratotomies conducted manually (M-AK) or assisted by femtosecond laser (F-AK), and intrastromal arcuate keratotomies (F-iAK). Outcomes of cost were selected from a patient perspective considering the gross cost of each one of the surgeries at European centers, and the effectiveness variable was the probability of achieving a visual acuity of 20/20 postoperatively. A sensitivity analysis was conducted to assess the uncertainty considering the evidence retrieved from the transition probabilities of the model, effectiveness, and cost.
RESULTS: F-AK or toric IOLs were the most effective treatments, increasing an 16% or 9%, respectively, in the percentage of eyes attaining 20/20 vision. The M-LRI, F-iAK, and F-LRI procedures were strongly dominated while the M-AK and toric IOL were weakly dominated by the F-AK. A patient with low corneal astigmatism would need to be willing to pay 360€ (95% CI, 231-1224) with F-AK and 472€ (95% CI, 149-4490) with toric IOLs for a 10% increase in the probability of achieving 20/20 vision.
CONCLUSIONS: From patient perspective, F-AK was generally the most cost-effective treatment, although toric IOLs can dominate in some countries.
