Piggyback intraocular lens implantation

Current Opinion in Ophthalmology, 2000
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 ...

Intraocular lens implant exchanges

American Intra-Ocular Implant Society Journal, 1985
We reviewed 23 consecutive cases of intraocular lens implant exchange. Lens dislocation (26%) and chronic intraocular inflammation (26%) were the most frequent indications for lens exchange. Post-exchange vision was best in those eyes treated for inappropriate implant power (100% less than or equal to 20/40), intermediate in dislocation cases (83% less

Secondary Intraocular Lens Implantation

Ophthalmology, 1983
The visual, refractive, and surgical results with 190 consecutive secondary implantations of an anterior chamber intraocular lens were studied. Best-corrected postoperative visual acuity was either better than or within 1 Snellen line of best-corrected preoperative vision in 87% of the cases. Vision worsened by more than two Snellen lines in ten cases (

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.

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 ...

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 ...

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
