Navigating Intraocular Lens Surgery with Discover Vision

IOLs or Intraocular lenses are plastic lenses that are surgically placed inside a patient’s eyes, typically after the patient chooses to have cataract surgery to improve their eyesight. During this treatment, a surgeon will remove your natural lens from your eye and replace it with an IOL made of durable plastic. Refractive defects may be corrected by some IOLs.

What Purposes Do IOLs Serve?

IOL implants are used in conjunction with cataract surgery. When the eye’s lens becomes clouded, it develops a cataract. You can have a fuzzy or foggy vision if you have this illness. Your natural eye lens will need to be replaced because cataract surgery destroys it, therefore you’ll need one to get your eyesight back. An ophthalmologist can replace your eye’s cloudy natural lens with a clear IOL. The replacement aids in clearing up blurry vision.

After cataract surgery, several IOL types can cure refractive problems such as presbyopia. To restore the eye’s capacity to concentrate on adjacent objects in these situations, an artificial lens is inserted into the eye. If you would prefer not to use near-vision glasses after cataract surgery, IOL implants can be an alternative. IOLs can be used to cure astigmatism, which impairs vision of both up-close and faraway objects.

How Are IOLs Made?

The materials used to make intraocular lenses have changed throughout time, moving from the early stiff polymers to the flexible silicone or acrylic used today. Your surgeon will take into account materials with the required qualities for the best possible eye safety and health when choosing IOLs for cataract surgery. The fact that stiff IOLs for cataract surgery necessitate a wider corneal incision is the main problem with them. In comparison, a much smaller incision is required to introduce foldable IOLs. Longer incisions may require more time to heal and may be more prone to infection.

Some of the most popular artificial lenses for this procedure are IOLs made of silicone and hydrophobic acrylic. They can be folded, and they also have little water (between 1 and 4 percent) in them. In a similar vein, contemporary IOLs contain a transparent UV layer that aids in shielding the eyes from sun damage.

IOL categories

The best IOL for your eye will be determined by your post-cataract surgery vision correction needs. Principal things to think about are:

  • Refractive error type, e.g., nearsightedness;
  • Existence of numerous refractive defects, including far- and nearsightedness.

The most typical IOL kinds are:

  • Single-focus IOLs
  • Convenient IOLs
  • Multiple focal IOLs
  • Toric eyewear

How Do IOLs Function?

Since each person is given an intraocular lens implant that corresponds to their refractive defect, every IOL is unique for them. IOLs from Discover Vision perform the same task as natural lenses. The IOL directs light that enters the eye toward the retina.  Similar to prescription glasses or contact lenses, it can treat farsightedness or nearsightedness.
