Piggyback intraocular lens implantation
Current Opinion in Ophthalmology, 2000The 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 ...

Super-reversed intraocular lens
Journal of Cataract and Refractive Surgery, 1990An intraocular lens (IOL) with an inverse (reversed) optic has the convex surface directed toward the retina, a design which has many advantages. We have developed a "super-reversed" IOL by increasing the angle of the haptic from 10 to 20 degrees and by increasing the convexity of the posterior surface (necessitating a concave anterior surface).

Intraocular lens complications.
Annals of ophthalmology, 1990The authors implanted intraocular lenses (IOL) in 780 eyes and considered complications of this surgery, dividing the complications into intraoperative and postoperative, the latter early and late. The most frequent intraoperative complications were: hyphema, vitreous injury, pupil deformation with an IOL in the anterior chamber (AC), and hyphema and ...

Intraocular Lens Dislocation, Intraocular Lens Exchange and Secondary Intraocular Lens Fixation
2016The incidence of intraocular lens (IOL) dislocation is increasing as with the changes in surgeons’ preference to newer IOL designs, introduction of soft IOLs and increased number of pseudophakic population in these years. Late decenteration is more frequently found in cases with uveitis cataract, pseudoexfoliation syndrome, and previous vitrectomy ...

Intraocular lens quality control
American Intra-Ocular Implant Society Journal, 1982A mislabeled lens was found to have a diopter power of 19.66 on the optical bench, although it was labeled as a 13.00 diopter lens. Both the surgeon and patient were unnecessarily frustrated. In addition, three consecutive posterior chamber lenses examined from one manufacturer showed poor loop quality.

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.

Intraocular lens implant exchanges
American Intra-Ocular Implant Society Journal, 1985We 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

Intraocular Lens Glucose Sensor
Diabetes Technology & Therapeutics, 2000Ocular spectroscopy, which is the use of the eye to monitor optically the concentration of metabolites in the body, has been successfully applied to monitor aqueous humor glucose concentration. In the United States, 1.7 million intraocular lenses are currently implanted yearly.
