Bilateral Intraocular Lens Implantation

Ophthalmology, 1983
A study of 1796 consecutive cataract patients in a posterior chamber intraocular lens implant (IOL) series revealed 373 patients (20.8%) who had bilateral IOLs. Visual acuity was 20/40 or better in 87% of first eyes operated and 90% in second eyes. The major cause of vision less than 20/40 was senile macular choroidal degeneration in both first and ...

Secondary intraocular lens implantation

Journal of Cataract and Refractive Surgery, 1987
We conducted a retrospective study of our first 75 consecutive patients receiving secondary intraocular lens implants. Ninety-seven percent had postoperative visual acuities of greater than or equal to 20/40; 86%, greater than or equal to 20/25. Four percent of patients lost two or more lines of vision.

Piggyback Intraocular Lens Implantation

2002
The piggyback method of implanting two intraocular lenses in one eye has been successfully expanded to address pseudophakic refractive error in normal eyes and eyes that have undergone post-penetrating keratoplasty. Piggyback implantation has been combined with the use of newly available minus-power lenses to provide appropriate power for a cataract ...

Tinting of Intraocular Lens Implants

Archives of Ophthalmology, 1982
Intraocular 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, 1978
ABSTRACTIntraocular 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

Piggyback intraocular lens implantation

Journal of Cataract and Refractive Surgery, 1998
Piggyback intraocular lenses (IOLs), used in eyes requiring high IOL powers, are generally implanted in the capsular bag. Proper position of the IOL loops is, however, an unresolved issue. In this case of piggyback implantation in both eyes of a patient, the loops of the second IOL were positioned at an axis between 45 and 60 degrees away from those of

Cytopathology of Intraocular Lens Implantation

Ophthalmology, 1985
The cytopathology of intraocular lens (IOL) following implantation is reviewed. A newly placed implant attracts macrophages and these settle on its surfaces to form optically clear membranes composed of so-called fibroblast-like cells and a film of proteinaceous material. The membranes apparently become tougher and more firmly adherent with time.

Secondary Intraocular Lens Implantation

Ophthalmic Surgery, Lasers and Imaging Retina, 1977
SUMMARY 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 calculation formulas for new intraocular lens implants

Journal of Cataract and Refractive Surgery, 1987
Several 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.
