Enhancing visual outcomes with advanced intraocular lenses (IOLs) in cataract surgery
While there is nothing wrong with a monofocal lens, this lens can deliver good vision only for one focal point either near, distance or intermediate. This lens is fully covered by the insurance companies for use in cataract surgery. This is best if budget is a concern or the patient does not mind wearing glasses after cataract surgery.
Premium lenses can correct the astigmatism, can provide multiple focal points and provide an extended range of vision. If the cornea is not completely round as occurs in astigmatism, the rays of light do not come to a point focus and the image is distorted. A toric IOL can get rid of this astigmatism. When the patient does not wish to use glasses for reading one can suggest multifocal IOLs which have multiple visual focal points. Vision is clear for both near and distance, but these are set points. The most advanced group of IOLs are the extended range of vision IOLs which can deliver the vision across a focal range and not just set points. In addition, these lenses can adjust for minor residual errors of refraction. They also have less glare and haloes that may be present with multifocal IOLs.
The Tecnis Symfony is an extended range of vision IOL which provides excellent visual results. The advantages of this IOL is a sharper vision, smooth transition between near, intermediate and distance vision and less incidence of lights and halos following surgery when compared to multifocal lenses. This is one lens which has satisfied numerous patients. The lens can correct any existing astigmatism also and comes in a toric form also. This lens has provided the greatest satisfaction and met the expectations of many patients.
