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 ...

3. 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 ]

   en.wikipedia.org/wiki/Intraocular_lens

   Intraocular lens. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...

6. Manual small incision cataract surgery - Wikipedia

   en.wikipedia.org/wiki/Manual_small_incision...

   Manual small incision cataract surgery. Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.

7. Phacoemulsification - Wikipedia

   en.wikipedia.org/wiki/Phacoemulsification

   Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure. This procedure minimises the incision size and reduces ...
