First results of cataract surgery and implantation of negative power intraocular lenses in highly myopic eyes.
OBJECTIVE
To determine whether cataract surgery in highly myopic eyes should be considered high-risk surgery and whether exact intraocular lenses (IOLs) should be implanted if negative power is required. SITE: Klinik Dardenne, Bonn-Bad Godesberg, Germany.


METHODS
We retrospectively studied 32 eyes of 27 highly myopic patients who had cataract surgery and posterior chamber IOL implantation. Intraocular lens power varied from -1.0 to -8.0 diopters (D), and eye length varied from 31.0 mm to more than 35.0 mm. Follow-up ranged from 6 to 36 months. Patients were analyzed for postoperative visual acuity and for intraoperative and postoperative complications.


RESULTS
No patients experienced intraoperative complications. Posterior capsule opacification, which occurred in 14 eyes, was the only postoperative complication in the anterior or posterior segments. Ninety-four percent of eyes achieved improved best corrected visual acuity, and 69% of eyes were within 1.0 D of the refractive target.


CONCLUSIONS
Cataract surgery can be performed in highly myopic eyes without intraoperative complications. A posterior chamber IOL should be implanted for postoperative refraction and intraocular stability, even if negative lens power is required.
