Glued IOL

What are indications of Glued IOL?

Traumatic Cataract, Aphakia, any complications during Cataract surgery, Subluxated Cataracts, Subluxated or Dislocated IOLs.

1. An Insight into Different Intraocular lens types

   IOLs, or intraocular lenses, replace your natural lens in order to create a uniform curve from the centre of the eye to the margins or the periphery. Monofocal, multifocal, and toric IOLs are the three types of available IOLs.
   The optimum of IOL depends on the level of focus required for your specific treatment. Below we have given a brief overview of four IOL lens types used in an IOL surgery:

2. Monofocal IOLs

   Monofocal intraocular lenses are one of the most widely used options for fixing incorrect vision. These lenses sharpen only one focus (near, far, or intermediate). However, it is not used to correct astigmatism.
   Monofocal IOLs are most commonly used to improve distance vision. In such cases, near-sighted vision tasks may still necessitate the use of “reader” glasses. On the other hand, monofocal IOLs could prove to be a good option for people who have:

   • Cataracts in both the eyes

   • These IOLs can be used for macular degeneration, which is an eye condition that creates blurry vision.

   • A limited budget which is mostly covered by the insurance plan.

3. Multifocal

   Multifocal intraocular lenses are considered to be the most useful of all lenses as they correct close, intermediate, and distance focus at the same time. Because the brain must be optimally trained to catch on with the needed vision information for either near or distant objects, most multifocal IOLs require an adequate adjustment period.

   Many people opt for multifocal lenses, which have two separate settings in each eye (near and distant). To generate a single image, the brain frequently combines and modifies both fields of vision. This option is not suitable for everyone because it requires each eye to function separately.

   If you’re looking for a solution to the following problems, multifocal lenses might be the way to go:

   • If you are suffering from age-related farsightedness or presbyopia.

   • If you want to free yourself of contact lenses and glasses.

   • If both your eyes have the good visual capability.

   • This setting, however, may cause issues like depth perception and problems with night vision.

4. Toric

   Toric lenses can help with distance focus and astigmatism treatment. An unevenly shaped cornea causes astigmatism, which often leads to blurred vision. Simply put, toric IOLs are designed specifically to correct the asymmetry caused by astigmatism.

   Below we have mentioned a few ways in which toric lenses are different from multifocal and monofocal lenses:

   • Toric lenses contain specific peripheral indicators that help with accurate astigmatism correction.

   • Toric lenses do not raise the risk of complications that arise from cataract surgery (such as eye inflammation or light sensitivity)

   • On the other hand, it is imperative to keep in mind that a misaligned toric IOL can result in hazy vision that is difficult to rectify with glasses.

5. Phakic Lenses

   In simple terms, phakic lenses are not IOLs but ICLs. The natural lens is left undisturbed and intact while using Phakic ICLs. A phakic ICL is a clear lens surgically inserted behind the iris, in front of the person’s natural lens, to correct severe to moderate near-sightedness.

   Without the use of extra corrective eyewear, this implant allows light to focus accurately on the retina. People who are too nearsighted for photorefractive keratectomy or LASIK should consider the option of getting a phakic ICL.

6. What are the advantages of Glued IOL?

   • The IOL is placed in the normal anatomical position 

   • The stability of the IOL is good

   • This procedure brings the eye back to 90% normal
