It is a technique where the intraocular lens is placed in the normal anatomical position by using glue when the capsular support is not there to place it, thereby bringing back the optics of the eye to normal.
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:
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:
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:
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:
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.
The quality of vision is not good with thick corrective glasses. You will have to wear a + 10 D glass which creates a lot of distortions. It reduces the field of vision, you will struggle with depth perception even after correction with lenses.
It should be done in a centre where there is a vitrectomy unit available. It’s best to choose a secondary or a tertiary hospital.
It will take about 20 minutes to 1 hour.
The vision improves the next day and by a week’s time it would return to normal.
Yes. You can lead a normal quality of life.
Lens replacement surgery (RLE) is a viable option for people who are irritated by their diminishing vision. In layperson terms, RLE is a technique for correcting vision.
For people with both short and long-sightedness, the surgery is permanent and absolutely safe. You may undertake natural lens replacement surgery if you have cataracts, astigmatism, presbyopia, or a dependency on varifocal, bifocal, or multifocal contact lenses/ glasses.
An IOL surgery or lens implant is a process of replacing the natural lens with an acrylic lens in your eye, which eventually over the image-focusing function. The IOL focuses light within the eye in the same way that the natural lens does.
IOLs can address a wider spectrum of visual issues than any other type of vision correction surgery. Astigmatism, myopia, presbyopia, and hyperopia can all be corrected with an IOL surgery. In most cases, however, an IOL is utilised to correct vision as part of Refractive Lens Exchange or a cataract surgery.
It will take around eight to twelve weeks for you to fully recover from the IOL surgery. During the period, keep the following things in mind:
While any operation carries the possibility of complications, difficulties following an intraocular lens implant or an IOL surgery are usually uncommon. Your ophthalmologist will carefully examine your eyes and review your medical history before carrying out any surgery to see whether you are fit for an IOL surgery. This can also help you figure out whether there are any factors that could make you more vulnerable to IOL hazards.
Redness, bleeding, and inflammation are some of the many possible side effects of IOL surgery, although they should go away in their natural course of time. A detached retina, severe inflammation, or infection, all of which might result in visual loss, are more serious side effects of this surgery. However, they are not a common occurrence.
Following your IOL surgery, your doctor may prescribe some medicated drops. To avoid infection or inflammation, make sure you take these drops exactly as directed by the doctor.
