Purpose:
To present own experiences in cataract surgery in myopic eyes.
Methods:
72 eyes of patients, aged 41-84, with 4-year follow-up were analysed. According to the degree of myopia, the patients were divided into 3 groups: MP up to -4.0 D (29 eyes), mp from -4.25 D to -8.0 D (27 eyes) and MP > -8.0 D (16 eyes). Extracapsular cataract extraction was performed in 55 eyes (76.4%) and intracapsular in 11 (15.2%). Posterior IOLS were implanted in 30 eyes (41.6%), anterior IOLS (including 4 secondary ones) in 26 (36.1%) and 16 eyes (22.2%) were operated on without IOLS implantation.
Results:
Good visual acuity (> 0.5) was achieved in 73.6% of cases, useful visual acuity (> 0.1) in 89%. The results as well as the postoperative complications were compared with the control group of non-myopic eyes. Glaucoma was observed in 18% of myopic eyes and in 10% of non-myopic but it was not significant.
Conclusion:
The safest method of cataract surgery in myopic eyes is extracapsular extraction with posterior IOL implantation. These eyes should be operated on by very experienced surgeons.
