Corneal refractive surgeries for the correction of myopia, hyperopia, astigmatism and hyperopia are quick and effective procedures, and have been growing in popularity over the last two decades. However, post-surgery corneal ectasia remains one of the most feared surgical complications. This is where the biomechanical integrity of the cornea begins to fail, with progressive thinning of the stro...

M anagement of astigmatism at the time of cataract or refractive lens surgery has evolved to include arcuate keratotomy and toric intraocular lens (IOL) implantation. Integration of preoperative corneal diagnostic instrumentation via Streamline digital wireless connectivity to the LENSARTM femtosecond laser (LENSAR Inc., Orlando, FL, US) now allows improved precision and accuracy of arcuate inc...

In 1792, a priest in Germany consulted a young doctor about a buried corneal foreign body hidden in a small, hard mass that partly covered the pupil. During removal of the foreign body, the doctor inspected the corneal incision with a microscope to confirm the suspected presence of the foreign body. This may be the first use of a microscope in eye surgery.

BACKGROUND This study evaluates patients with congenital aniridia and cataract who underwent phacoemulsification, capsular tension ring placement, and foldable intraocular lens implantation. METHODS In this prospective case series, 10 patients (17 eyes) underwent cataract surgery via a 3.2 mm clear corneal incision. A continuous circular capsulorhexis with <6 mm diameter was employed. A capsu...

Intralamellar keratoplasty in inbred rats is a valuable method for the investigation of corneal allograft rejection. Present methods of intralamellar corneal grafting are tedious and time-consuming. In addition, induction of neovascularization, a prerequisite to inducing graft rejection, is variable. In an effort to overcome these problems, the authors have developed an improved method of intra...

OBJECTIVE To compare the efficacy and safety of the intraocular lens (IOL)-shell procedure versus conventional phacoemulsification for the surgical treatment of dense cataracts. METHODS Eighty eyes with dense nuclear cataracts were enrolled in a prospective, randomized controlled study. Patients were assigned to two groups. In Group I, the IOL was traditionally implanted after all nuclear fra...

The implantation of a phakic intraocular lens (IOL) for the correction of moderate or high myopia has theoretical advantages in comparison with corneal procedures and clear lens extraction, such as precision and stability not dependent on the corneal healing process, a wider range of correction, magnification of the intraocular image, and preservation of accommodation. However, these lenses hav...

The capsule of the crystalline lens, if sufficiently present, is used as a support tissue for intraocular lens (IOL) implantation surgery performed on vitrectomized eyes. Eye trauma or iatrogenic damage during complicated cataract surgery, loss of position and zonule connections of the crystalline lens, and IOL via dislocation may cause loss of support tissue for lens capsule implantation prior...

PURPOSE To study the effect of cataract surgery through 3.2 mm superior incisions on corneal aberrations with 2 types of monofocal intraocular lenses (IOLs) with an aspherical design. SETTING Instituto de Optica, Consejo Superior de Investigaciones Científicas, and Fundación Jiménez Díaz, Madrid, Spain. METHODS Corneal topography of 43 eyes was obtained before and after small corneal incisi...
