Implantable Contact Lens (ICL)
ICL corrects higher degree of refractive error which cannot be done by laser treatments. Implantable contact lenses (ICL spherical /Toric) is surgically implanted in the eye between the iris and the natural crystalline lens through a small corneal incision.
Refractive lens exchange
In refractive lens exchange surgery the natural crystalline lens of the eye is replaced with an artificial Intra ocular lens (IOL) to achieve sharper focus, rarely it is opted for young people with very high powers.
The surgical procedure is almost the same as cataract surgery and is done under local/topical anesthesia.
Instruments Available
Orbscan corneal topographer, Zywave Aberrometry, Specular microscope, Keratometer (auto/manual), Ultra sound Pachymeter
Aberration free/ Aspheric IOLS
These IOLs gives good quality of vision post operative due to the lens design, it also improves the contrast sensitivity of the patient and good night vision. These lenses also filter the harmful UV light and blue light which are said to be harmful to the retina.
Toric IOLS These IOLs
correct the pre existing corneal astigmatism there by reducing the possibility of spectacle wear for distant vision post operatively.
Multi-focal IOLs
These IOLs provide clear vision for all distances hence almost 90% of the day-to-day activities can be performed without the need for additional glasses. Rarely the patient may experience glare during nights post operatively but usually gets adapted within a few months.
Accommodating IOLs
These IOLs have flexible hinges that enables them to change focus for different distances hence providing clear distance, intermediate and near vision without glasses.
