A cataract is a cloudiness of the normally clear lens that sits in the front part of the eye. The lens in located inside of the eye, behind the iris, the colored part of the eye, but in front of the vitreous cavity. The lens focuses light rays on the retina in the back of the eye to produce a crisp image of what we see.
As the cataract increases in density and cloudiness, vision is often impaired. Clouded vision may make it more difficult to read, drive a car or perform daily activities. Cataracts develop slowly over time and are a natural result of aging. Cataract surgery is very common and is the only way to remove a cataract.
Cataracts Video Series
In our series of four videos, you will discover what cataracts are, understand how they affect your vision, explore treatment and lens options for cataracts, and learn about the LenSx® Laser System used in laser-assisted cataract surgery.
What are the Symptoms of Maturing Cataracts?
- Blurry or dim vision
- Poor night vision
- Halos around lights
- Sensitivity to light and glare
- Need for brighter light for reading and other activities
- Frequent need to change eyeglass prescriptions.
Cataract development can be accelerated by trauma, diabetes and other long-standing medical conditions, use of certain medications, and genetic factors.
Cataract Surgery
Cataract surgery is very common and is the only way to remove a cataract. In fact, cataract surgery is the most commonly performed surgery in the United States.
There are no medications, eye drops, exercises or glasses that will remove the effect of cataracts on vision once they have formed. Surgical removal of the cataract is indicated when the visual impairment due to cataracts impacts the patient’s quality life.
The goal of cataract surgery is to replace the cloudy lens with a permanent, transparent, intraocular lens, made of a specialized plastic. Your cataract surgeon places the new lens in the exact anatomic location where the natural lens once was. Any power lens can be implanted into the eye, resulting in a decreased dependence on glasses after cataract surgery. After the cataract is removed, it cannot return.
Cataract Surgery Quick Facts
- Cataract surgery is performed one eye at a time
- The two surgeries are usually separated by several weeks.
- Dr. Lally performs cataract surgery in an operating room at an outpatient surgical center.
- She uses an operating microscope and microsurgical instruments to perform the surgery.
- A small incision is made on the side of the eye and specialized instruments are used to fragment and suction the cloudy lens from the eye.
- The back membrane of the lens (called the posterior capsule) is left in place and the plastic intraocular lens implant will be placed inside the capsular bag.
- The incision is made in such a precise way that usually, no sutures are required at the end of the case.
Prior to the surgery, a series of precise measurements are taken using laser technology and theoretic calculations are done to aid the surgeon in selecting the desired lens power. Despite the precision of the measurements, there is no absolute guarantee of the final vision result. There are many factors that go into the patient’s post-operative visual acuity, including final position of the intraocular lens, individual healing and scarring patterns and slight irregularities in an individual patient’s pre-operative calculations.
Over 98% of cataract surgeries result in improved vision. A small number of patients however may have problems and/or complications including infection, bleeding, persistent swelling, lens dislocation and retinal complications.
YAG Capsulotomy
Following cataract surgery, approximately 10-50% of patients will develop clouding of the posterior capsular membrane within months to years following cataract extraction. The capsular bag is a very thin layer of tissue that acts as a scaffold for holding the implanted intraocular lens in place. With time, cells collect on the capsular bag and create visual clouding. This phenomenon is sometimes referred to as a “secondary cataract”, but this terminology is a misnomer- the clouding is due to capsular haziness, not the development of another cataract.
If the cloudiness from the capsular membrane causes decreased vision, a YAG laser can be used to precisely remove the clouded membrane. Dr. Lally performs this procedure in the office. It is completely painless and can be completed in roughly 10 minutes with no associated down-time or need for post-laser medication. Patients will notice floaters in their vision after the laser, but they will gradually resolve over several days. As with any surgery or procedure, there are possible risks and complications with YAG capsulotomies. These include swelling, increased eye pressure, movement or dislocation of the intraocular lens dislocation and/or retinal tears or bleeding.
Premium IOL Options For Cataract Surgery
During cataract surgery, the natural lens of the eye, once it has become cloudy, is removed and replaced with a clear artificial lens called an intraocular lens (IOL). This lens is permanent and is carefully selected to match your visual needs and lifestyle. Choosing the right lens is an important part of the procedure and can significantly impact how well you see after surgery.
There are three main categories of intraocular lenses. Monofocal lenses provide clear vision at a single distance, most commonly set for distance vision, meaning patients will typically still need glasses for reading or intermediate tasks. These lenses offer excellent image quality and remain the most commonly used option.
Multifocal lenses, including extended depth of focus (EDOF) designs, are intended to reduce dependence on glasses by providing a range of vision, from distance to intermediate and sometimes near. These lenses use advanced optical technology to distribute focus across multiple distances, though some patients may notice visual phenomena such as halos or glare, particularly at night.
Toric lenses are designed for patients with astigmatism. They correct irregular curvature of the cornea, allowing for sharper, clearer vision without relying as heavily on glasses for distance. Toric lenses can also be combined with monofocal or certain extended depth of focus designs, depending on individual needs.
During your consultation, we will discuss your daily activities, visual priorities, and eye health to help determine which lens option is best suited for you.
