OBJECTIVES: To model the lifetime cost attributed to intraocular lenses (multifocal vs. monofocal) implantation during cataract surgery from patient’s perspective. METHODS: The Markov model was developed with 28-day cycle length projecting life-time costs of patients undergoing cataract surgery of both eyes at 65 years. Patients move among four health states which occur after cataract surgery. Patients become independent on the spectacles or need them after cataract surgery with probabilities derived from literature. In the model, we assume that new glasses are bought by patients, who wear glasses after surgery, every three years. Patient may die from each health state with probability derived from Czech life-tables there was no difference in mortality specific for particular intraocular lenses. Resource utilization was received by an expert panel and unit costs were derived from current pricing list. Costs of cataract surgery with multifocal and monofocal lenses implantation were 1,200EUR and 9.9EUR, respectively. Mean costs of spectacles were 48.9EUR and 82.5EUR after the intervention of implanting multifocal and monofocal lenses, respectively and monthly costs of ophthalmologist visit, maintenance and service of spectacles was 0.4EUR. Discount rate of 3% was applied. One-Way Sensitivity Analysis was performed.  RESULTS: After cataract surgery with multifocal lenses implantation, patients purchase on average by 4.4 spectacles less compare to patients undergoing monofocal intraocular lenses implantation (i.e. 5.9). The initial patient’s investment of 1,190EUR into multifocal IOLs is in the lifetime horizon partially offset by saving of 364EUR attributed to lower number of new spectacles purchased and their maintenance. Costs on spectacles after cataract surgery with monofocal lenses and level of reimbursement of multifocal lenses were the biggest driver of the results.  CONCLUSIONS: Bilateral multifocal IOL implants decrease patient’s dependence on spectacles. From patient’s perspective, the initial investment into multifocal lenses is partially compensated by saving of spectacles costs and its maintenance.
