Bag-in-the-lens implantation of intraocular lenses
Journal of Cataract and Refractive Surgery, 2002To report a new intraocular lens (IOL) and an IOL implantation concept, the bag-in-the-lens implantation technique, designed to prevent posterior capsule opacification (PCO).The University of Antwerp, Department of Ophthalmology, Edegem, Belgium, and the Netherlands Ophthalmic Research Institute, Department of Morphology, Amsterdam, The Netherlands ...

Tinting of Intraocular Lens Implants
Archives of Ophthalmology, 1982Intraocular lens (IOL) implants of polymethyl methacrylate (PMMA) lack an important yellow pigment useful as a filter in the visual process and in the protection of the retina from short-wavelength radiant energy. The ability to produce a yellow pigment in the PMMA used in IOL implants by exposure to near-ultraviolet (UV) light was tested. It was found

Intraocular Lens Implantation: A Review
Artificial Organs, 1978ABSTRACTIntraocular lens implantation has been developing over the past 15 years in Europe and is now becoming popular in the United States. Lens materials and designs as well as surgical techniques are still being evaluated. The overall results are excellent, with a small increase in complications being the price paid for a dramatic increase in visual

Intraocular lens implantation in microphthalmic patients
Journal of Cataract and Refractive Surgery, 1992Microphthalmos is a developmental disorder of the eye consisting of a smaller than normal eye. This disorder can present as an isolated condition or associated with other systemic alterations. It is not uncommon for patients with microphthalmos to have congenital cataracts along with other ocular and systemic abnormalities.

Secondary Intraocular Lens Implantation
Ophthalmic Surgery, Lasers and Imaging Retina, 1977SUMMARY Mere aphakia is not an indication for secondary intraocular lens implantation. However, many patients with positive indications may be benefited most strikingly by this procedure. These indications are illustrated and results of the author's first 65 secondary implantations are analyzed.

Intraocular lens implantation and high myopia
Journal of Cataract and Refractive Surgery, 1988We evaluated aphakia and pseudophakia in highly myopic patients whose axial lengths were 27 mm and over. Cataract surgery alone was performed on 99 eyes (aphakic group) and intraocular lens (IOL) implantation was performed on 84 eyes (pseudophakic group). The IOL power was determined by the SRK formula and ranged from +9.0 to +18.5 diopters (D).

Intraocular lens calculation formulas for new intraocular lens implants
Journal of Cataract and Refractive Surgery, 1987Several different formulas are available for preoperative calculation of the required implant power for a desired postoperative refraction. However, the application of both theoretical and statistically derived regression formulas to the new generation of soft intraocular lens implants poses several difficulties.

Primary Intraocular Lens Implantation
2020Primary intraocular lens (IOL) implantation is performed when a cataract is removed and an IOL is implanted at the time of cataract surgery. Lensectomy is recommended for any visually significant lens opacity in a child. Patients who are less than 7 months of age are left aphakic in the developed world.

Changing Trends in Intraocular Lens Implantation
Archives of Ophthalmology, 1989Congress and the Health Care Finance Administration have recently targeted cataract extraction procedures for particular scrutiny and cost containment. The reasons have been amply stated: cataract surgery now accounts for 12% of the entire Medicare budget and is presently the most frequently performed surgical procedure reimbursed by Medicare.

A modified lens glide for intraocular lens implantation
American Intra-Ocular Implant Society Journal, 1980The sheets glide has been narrowed and bent 30 degrees; this model is shorter than the original design. With rotation the bend produces an effective angle up to 85 degrees for hooking the iris at 12 o'clock during glide removal, and thus allowing the superior lens loop to be simultaneously dropped behind the iris.
