Purpose

To analyze the refractive and visual outcomes after cataract surgery with the implant of Puresee lens at long, intermediate and near distances. To evaluate the predictability of the technique. To define the efficacy and safety indexes.

Setting

Prospective study of consecutive case series in one single clinical site

Methods

Prospective study of patients who underwent cataract surgery by phacoemulsification technique and implant of the Puresee lens. After a month, refractive and visual outcomes (decimal scale) were evaluated:  Monocular uncorrected and corrected distance visual acuity (UDVA and CDVA) (6m), binocular uncorrected intermediate visual acuity (UIVA) (66 cm) and binocuar uncorrected near visual acuity (UNVA)  (40 cm). Defocus monocular curve was obtained, such as the efficacy and safety indexes.

Results

118 eyes of 59 patients were included. The mean age was 69.03±8.81 years old. The mean spherical lens power was 20.5±4.04 dyopters(D), and a range from 11.5 to 30 D. 52.5% were toric lenses and 47.5% were spherical. The mean preoperative CDVA was 0.82±0.22. Postoperative outcomes after a month: Monocular UDVA 0.90±0.15, monocular CDVA 0.97±0.08, binocular UIVA 0.87±0.19 and binocular UNVA 0.66±0.14. UDVA was equal or better than 0.8 in 80.5% of patients. UNVA was equal or better than 0.6 in 75.6% of patients. The mean postoperative sphere was -0.11±0.38. Efficacy and safety indexes were 1.10 and 1.18 respectively.

Conclusions

These outcomes highlight that the implant of the Puresee lens is a predictable, effective and safety procedure, reaching good levels of visual acuity at far, intermediate and near distances, and allowing independence of refractive correction at a functional near vision. High tolerance to refractive error provides a good uncorrected visual acuity at far distance in a high percentage of patients.
