Purpose:
To evaluate the posterior opacification (PCO) rates in three different modern standard intraocular lenses (IOL) and analyse the related cost.
Setting:
Department of Ophthalmology, Blekinge Hospital, Karlskrona, Sweden.
Methods:
Retrospective study of medical records from 1527 patients who underwent uneventful cataract surgery by phacoemulsification with posterior chamber implantation of either AcrySof SN60 (n=375), Akreos Adapt (n=350) or Tecnis Acryl IOL (n=801). All surgeries were performed by the same surgeon using the same surgical technique and equipment. Primary endpoint was Nd:YAG capsulotomy for visual impairment secondary to PCO. The patient data collected were date of cataract surgery, follow up time, age, sex, diabetes without retinopathy, glaucoma, macular degeneration, death, postoperative iridocyclitis, performed Nd:YAG capsulotomy, time between surgery and Nd:YAG capsulotomy and postoperative retinal detachment. Cost of IOL material and Nd:YAG capsulotomy for PCO was then evaluated and compared between the IOL“s.
Results:
Mean follow-up was 41.5 months and the only statistically significant variable of developing PCO was IOL-type and individual follow-up time. Nd:YAG capsulotomy was performed in 7.47% in the AcrySof group, 17.71% in the Akreos group and 3.75% in the Tecnis group. Mean follow-up time was 41.4months for the AcrySof group, 33.1 month for the Akreos group, and 45 months for the Tecnis group. Average cost for Nd:YAG capsulotomy per surgery was 18.75 in the Acrysof SN60 group, 44.25 in the Akreos Adapt group and 9.3 in the Tecnis Acryl group.
Conclusions:
This retrospective study shows that the risk of PCO and Nd:YAG capsulotomy is significantly higher in hydrophilic Akreos IOL compared with both AcrySof and Tecnis hydrophobic IOL“s. The increased risk for PCO in the hydrophilic IOL is related to higher total average costs for cataract surgery. FINANCIAL DISCLOSURE?: No
