What Is The Ideal Cataract Lens Replacement For You?
With the introduction of top performing cataract lens replacement, any patient who underwent a cataract surgery can now have the privilege of getting the ideal intraocular lenses (IOLs) for his/her eyesight condition, unlike before where a patient had to wear thicker prescription eyeglasses or contact lenses just to see things clearer.
What is the right IOL implants for you?
There are various types of cataract lens replacement which are usually determined through the following conditions:
- Prior to the cataract eye surgery, the eye specialist will measure accurately the eyes of a patient to get a more accurate IOL power. Depending on the final eye analysis, the eye doctor will provide the best option which may include the selection from the various types of IOLs suitable to the patient’s eyesight problem.
- Your choice of lens replacement can also affect your overall visual capability without wearing the eyeglasses. Although, there are cases when the wearing of prescription eyeglasses to some patients are still needed for some activities.
- Patients with astigmatism are given other related treatments to solve their current eyesight problem as well as the possible use of toric IOLs.
- Overall cost of IOL implants may also become a major factor before a patient will decide the type of IOL implants he/she will avail. Specialized or advanced IOLs may cost more from the ordinary type of IOL, but these premium lenses may eliminate or reduce the need to wear prescription eyeglasses.
3 common types of Intraocular lens
This is the most common type of IOL and is the lens option covered by all insurance plans. With this type of IOL implant, the need to wear glasses for distance, intermediate, and/or near vision will be 100% for all levels of functional visual activity. Sometimes your cataract eye surgeon will select a “monovision” strategy wherein the IOL for one eye is set for near distance while the other set is for far distance. Persons who work most of their time in front of the computers, PDAs and other digital gadgets may find this technique more useful., but those most successful with this strategy are those who did monovision in contact lenses for years prior to cataract surgery, allowing for proper adaptation as the IOL monovision option is permanent.
There are the modern types of IOL lenses where the need for eyeglasses or contact lenses may be reduced or eliminated. The patient who decides to have the multi-focal type may see things or objects both near and far clearly. Although, the capacity to read or do other activities without glasses may vary from one person to another, in most cases of cataract treatments, the multi-focal IOLs are put in both eyes for optimum results. Lastly the entire success of an individual’s multi-focal replacement is also dependent on one’s pupil size and other health factors.
Toric lens for astigmatism
This is a monofocal lens with specialized features built into the lens to correct one’s astigmatism where the eyesight condition is distorted or blurred both on near and far distance. Eye doctors often suggest toric IOLs for patients with astigmastism, mostly ending up with a minimal need for eyeglasses for distance vision but full-time correction for all near vision tasks.
Additional tips and warnings
- If you are going to an eye surgery center near your area, ask the eye doctor what are the possible after-effects of a cataract lens surgery. There are instances wherein additional surgery is advised to replace an existing IOL for another type of IOL implant, so be aware of these potential scenarios.
- Patients who underwent an eye refractive surgery like Lasik must be assessed before having IOL replacements so that accurate IOL prescriptions will be derived. Technologies such as real-time intraoperative aberrometry, a laser-guided device, can be used to increase the precision in determining the proper IOL replacement especially after Lasik.
