To evaluate the results of clear lens extraction in patients with high myopia.
This is a descriptive and retrospective study, in which patients who clear lens extraction was performed from January 2003 to January 2005. Clear lens extraction with phacoemulsification (Legacy and Infinity) was used, and foldable lenses were inserted. The following criteria were taken preoperative and 3rd, 6th and 12th months after the procedure: uncorrected visual acuity (UCVA), best corrected visual (BCVA), with the logmar conversion, spherical equivalent (SE), intra–ocular pressure (IOP), specular microscopy, and cylinder power.
Thirty nine eyes of 25 patients were included. Eighty percent of patients had high myopia with middle age of 45 years old. The mean preoperative UCVA was 1.10 in 85% of cases, and 0.38 postoperatively and remain stable at 3, 6 and 12 months. The mean preoperative BCVA was 0.30 and 0.10 postoperatively. (p <0.003) Preoperative SE in average was – 9.66 D and – 2.84 D postoperatively (p<0.002). There was no change in IOP between preoperative and one year of follow up. Preoperative endothelial cell density was 2,205 cells/mm2 and 1,982 cells/mm2 (p<0.007). Preoperative cylinder power was – 2.54 D and – 1.78 D postoperatively (p<0.001). Only two complications (lens dislocation and capsule rupture) during the procedure were seen.
The clear lens extraction is an alternative method with satisfactory results for high myopic patients.
