Over 18 million people choose to restore their vision and undergo cataract surgery every year.1 Cataract surgery is a straightforward outpatient procedure that removes the clouded natural lens in your eye and replaces it with an artificial lens called an intraocular lens (IOL).
Multifocal IOL vs. Monofocal IOL: What You Need To Know
When selecting a lens, there are two general types of lenses to choose from: multifocal or monofocal lenses. Both will treat your cataract and reestablish your vision, but there are a few key differences.
A multifocal IOL is designed to correct both cataracts and presbyopia. Presbyopia is a common age-related condition. Beginning around the age of 40, the natural lens inside the eye begins to harden and becomes less flexible. This reduces the eye’s ability to switch focus from near to far to in between and back again, resulting in vision loss and, in most cases, the need for reading glasses or bifocals.
A multifocal lens has several different focus regions that are designed to allow you to see clearly up close, far away and in between, and, in most cases, will eliminate your need for glasses. After surgery, you may experience an adjustment period during which you may see rings around lights at night. This is normal, and as the eye adjusts to the lens over time, the visual impression of these rings typically lessens or goes away.
In contrast, a monofocal lens has only one focus region. It allows you to see objects far away, but you will continue to need glasses for reading and other up-close activities.

CORNEA TRANSPLANT
Corneal Transplant
Corneal transplantation is routinely performed to restore sight in patients whose corneas have suffered damage from conditions such as trauma, keratoconus, inordinate swelling and other corneal disorders. Over the years, more successful visual outcomes have been achieved through advancements in surgical technique as well as increased acceptance of donor tissue. At Vision NYC we perform a thorough examination of your eye and use your previous corneal history to aid us in deciding if transplantation surgery is an option which may offer you improved visual acuity.
In the past full thickness transplantation of the cornea (penetrating keratoplasty) was required to treat all of the above issues. In many instances it is still the procedure of choice. Newer techniques which involve transplantation of specific cornea layers offer improved visual outcomes with decreased risk of rejection of the donor tissue and quicker healing. Deep anterior lamellar keratoplasty (DALK) involves transplantation of the front layers of the cornea, whereas descemets stripping endothelial transplantation (DSEK) involves transplantation of the most posterior layers of the cornea. In cases of advanced ocular surface disease or previously failed cornea transplantation, one may elect to proceed with surgical placement of a prosthetic cornea (Boston Type I Keratoprosthesis).
Restoring one’s sight from successful corneal transplantation is truly a life changing experience and we at Vision NYC hope to make your experience a positive one.
Prosthetic Cornea
A prosthetic cornea is often used after standard corneal transplant has failed on more than one occasion, chemical injury, Stevens-Johnson Syndrome, or in cases of severe ocular surface disease. In conditions such as these a prosthetic cornea may provide some visual improvement. The Boston Keratoprosthesis Type I is often the prosthesis of choice. Having been granted FDA approval in 1992 the Boston Keratoprosthesis is the most commonly used prosthetic cornea in the United States as well as worldwide with over 7,000 implanted to date. This prosthesis is made with clear plastic and inserted into a corneal graft. The postoperative course for patients needing this surgery is rather protracted and careful and attentive management is required to optimize their visual outcome.
