Unlabelled:
Patients with high myopia represent a risk group in cataract surgery. They are suspected of having a higher incidence of retina problems after cataract surgery. In addition, IOL calculations may be difficult.
Method:
In a retrospective study data of 97 eyes of 60 high myopic patients were analyzed. The inclusion criterion was an axial length of > 26 mm. All eyes underwent cataract extraction and PC IOL implantation between 1991 and 1995. Evaluation focused on visual outcome, precision of the IOL power calculation and the rate of complications.
Results:
Visual acuity increased from 0.18 to 0.46 postoperatively. On average, myopia was reduced from -13.6 D to -3.0 D;66% of the patients were +/-1 D;86% were +/-2 D within the predicted calculation of postoperative refraction. During a follow-up period of 14.8 months no retinal detachment occurred.
Conclusion:
Cataract extraction and IOL implantation showed good functional results, and prediction of postoperative refraction was satisfactory. Our data support the studies reporting a low incidence of retinal problems in patients with high myopia.
