Different Types of Intraocular Lenses in Cataract Surgery

1. Different Types of Intraocular Lens (IOL)

2. Introduction With the rapid advancement of technology, the world of vision treatments has undergone revolutionary changes in recent times. Removal of cataracts may make the natural lens opaque. For restoration of vision to normalcy, intraocular lenses are implanted.  The intraocular lens is also popularly referred to as IOLs. Sir Harold Ridley implanted the first IOL in the year 1949. At that time, the material used in its construction was acrylic. In 1981 the USA Food and Drug Administration declared these lenses safe for human eyes.

3. Types of Intraocular Lenses Before having the surgical procedure, however, you will have to decide on the type of artificial lens you need. Multifocal Lens Monofocal Lens Toric Lens

4. 1. Monofocal Lens Among the numerous varieties of IOLs, Monofocal is the basic one. Monofocal lenses involve correcting one point of focus and aim rectification for one distance only (far or near) unless the monovision technique is applied. The monovision technique involves correction for both close as well as distance vision. This involves the dominant eye, being adjusted for distance viewing. Correction of the other eye is done for near viewing. 

5. 2. Multifocal Lens A popular choice is a multifocal lens. It gives a chance to the user to view from a closer range. Also, it provides an opportunity to correct Presbyopia. In most cases, you will not need to use glasses after cataract surgical procedures. Multifocal IOLs require an adjustment period because the brain must be trained to select needed vision information for either near or distant objects.

6. 3. Toric Lens Another type of premium lens worth mentioning is a Toric IOL. This design is devised for the correction of astigmatism disorders. Astigmatism is a refractive disorder that blurs vision due to the irregularly shaped cornea of the eye. If you have minor astigmatism, a Toric lens will be beneficial. The main advantage of using Toric Lens is that it reduces the risk of eye surgery complications such as light sensitivity.

7. Pricing Structure of IOL When choosing IOLs, the pricing structure is an important consideration. In general, cataract surgery is covered by insurance. However, not all kinds of IOL are covered. Only the Monofocal IOL is covered by insurance. Since, Multifocal and Toric lenses fall under the premium category, most insurance would not cover these costs and it will be an additional out-of-pocket expense for you.

8. Talk to the Doctor Seek an initial consultation with the doctors of any reputed laser eye centre in Delhi. A prudent approach is to conduct comprehensive research on the internet to obtain the names of leading clinics specializing in eye care treatments. They should have several years of experience in the implanting of these lenses.  You will need to exercise a cautious approach while selecting an IOL. Before making a selection, you will have to consider your lifestyle. Individuals who lead active lives may not want to wear glasses after their cataract procedure. Determine your requirements first. You may want to avail of options that will give you a scope to see effortlessly.
