Refractive Surgery for Myopia

This chapter describes current surgical techniques used to correct myopia, including laser correction (laser surgeries), incisional techniques, intrastromal corneal rings, phakic intra‐ ocular lenses, and refractive lensectomy.

Refractive surgery for hyperopia.

PURPOSE To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation. METHODS We operated on 184 eyes with hyperopia; 56 eyes had less than +2.00 D (lo...

FEBRUARY 2004 I CATARACT & REFRACTIVE SURGERY TODAY I 27 T he FEMTEC femtosecond (ultrashort pulse) ophthalmic laser (20/10 PERFECT VISION Optische Geräte GmbH, Heidelberg, Germany) is a photodisruptive laser. Although performed since the early 1980s, ophthalmic photodisruption has previously been limited to intraocular procedures because of the relatively large amount of energy needed to initi...

Refractive lens surgery.

This article compares methods of axial length measurement for determining intraocular lens power and describes bimanual micro incision phacoemulsification for refractive lens exchange and routine cataract surgery, which offers an enormous advantage of maintaining a more stable intraocular environment during lens removal. This advantage may be especially important in high myopes who are at a gre...
