2. Intraocular lens power calculation - Wikipedia

   en.wikipedia.org/wiki/Intraocular_lens_power...

   The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the ...

4. A-scan ultrasound biometry - Wikipedia

   en.wikipedia.org/wiki/A-scan_ultrasound_biometry

   A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan), uses an ultrasound instrument for diagnostic testing. [1] A-scan biometry measures the axial length (AL) of the eye prior to cataract surgery in order to assess the refractive power of the intraocular lens that will be implanted.

   Trief asks her patients to stop wearing soft contact lenses for one week prior to the pre-surgery measurements doctors take, since the lens can change the shape of the eye and affect the measurements.

6. Cataract surgery - Wikipedia

   en.wikipedia.org/wiki/Cataract_surgery

   Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1] The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.

7. Dilated fundus examination - Wikipedia

   en.wikipedia.org/wiki/Dilated_fundus_examination

   Cataracts: An often age-related condition that leads to gradual vision loss secondary to clouding of the lens. Examination may reveal opacification of the lens and often an absent or blunted red reflex. Dilated fundus exam allows for examination of more peripheral cataracts, as well as evaluating candidacy for cataract surgery. [9] [12]
