Abstract Details

Purpose:

A prospective study based on evaluation of 300 eyes of 150 patients. Patients with ophthalmic pathology which would affect the quality of postoperative vision were not included. Corneal astigmatism from 1D to 1.5D was treated by LRI. Patients with higher astigmatism were excluded. The SBL-3 is a hydrophilic acrylic presbyopia correcting lens. The IOL power was calculated using SRK/T formula. Patients were evaluated 4 years (±4 months) postoperatively for distance, intermediate (70cm) and near (40cm) visual acuity and monocular defocus curve examination was performed. A satisfaction questionnaire about photopic phenomena and evaluation of spectacle independence was completed.

Eye centre Prague

Methods:

A prospective study based on evaluation of 300 eyes of 150 patients. Patients with ophthalmic pathology which would affect the quality of postoperative vision were not included. Corneal astigmatism from 1D to 1.5D was treated by LRI. Patients with higher astigmatism were excluded. The SBL-3 is a hydrophilic acrylic presbyopia correcting lens. The IOL power was calculated using SRK/T formula. Patients were evaluated 4 years (±4 months) postoperatively for distance, intermediate (70cm) and near (40cm) visual acuity and monocular defocus curve examination was performed. A satisfaction questionnaire about photopic phenomena and evaluation of spectacle independence was completed.

Results:

Monocular UCDVA was 0.8 (decimal) or better in 94% of eyes, and 1.0 or better in 83% of eyes. Monocular UCIVA was 0.8 or better in 86% of eyes, and 1.0 or better in 40% of eyes. Monocular UCNVA was 0.8 or better in 94% of eyes and 1.0 or better in 62% of eyes. The photopic monocular defocus curve 4 years (±4 months) postoperatively shows continuous range of vision (visual acuity above 0,2 logMAR) up to -3D which corresponds to distance to 33cm. Thirty one percent of patients underwent Nd:YAG capsulotomy for posterior capsule opacification.

Conclusions:

SBL-3 patients report excellent visual outcomes and low levels of photopic phenomena. Patients receiving SBL-3 attained very good uncorrected visual acuity at all range of distances and gained spectacle independence. Also, preoperatively myopic patients that used to read without spectacles were very satisfied with the near vision after surgery.
