What is a Cataract?
Cataracts are cloudy or opaque areas of the eye lens that are usually transparent. Depending on the size and position, it can cause blurred vision. Most cataracts occur in people over 55, but sometimes in infants and young children as inherited genetic disorders. Usually, cataracts develop in both eyes, but one eye may have slightly worse vision than the other.
Early symptoms of cataracts include blurred vision, glare, and causes difficulty reading. In general, cataracts develop very slowly, and surgery may not need for years. In some cases, you can still have a good view if you change glasses or contact lenses regularly.
There is no way to prevent cataracts development. Currently, the only way to treat cataracts is surgical removal of the natural eye lens.
Cataract surgery is done on an outpatient basis by an ophthalmologist. Cataract operations can traditionally be done with ultrasonic energy to remove cloudy lenses, or they can be removed using laser technology. Cataract surgery is prevalent and a safe procedure.

Let us start with the cataract surgical procedure details:
Cataract Surgical Procedure:
Pre Operative Care:
Cataract surgeon will examine the eye, ask about your lifestyle to understand your expectations of surgery, and the type of vision you want after surgery. This review also helps your surgeon understand the types of lens you need. If you have cataracts in both eyes, your doctor will usually schedule a second operation after the first eye has healed.
Your doctor may also advise undergoing additional health checkup before surgery, and he might make a few suggestions:
Undergo tests: At least one week before surgery, your doctor will do a painless ultrasound test to measure the size and shape of your eyes. It helps to determine the correct type of lens implant (intraocular lens or IOL).
Stop taking certain medications: Doctor may advise stop taking some medication temporarily because this can increase the risk of bleeding during the procedure. Tell your doctor if you are using any medicines for prostate problems because some of these drugs can interfere with cataract surgery.
Use eye drops to reduce infection risk: One or two days before surgery, antibiotic eye drops prescribed by the doctor.
Dont eat before surgery: You may be asked not to eat or drink 12 hours before the surgery.
Preparation for your recovery: Usually you can go home on the same day of surgery, but you can’t drive. So make someone pick you back home, and also arrange a person to help at home as needed. Because the doctor advises limiting your activities such as bending and lifting after surgery for about one week.
On the day of the surgery:
- Make sure you wear comfortable clothes
- Don’t use make-up, cream or lotion on your face, especially avoid eye make-up
- You have to bring someone to drive you here or later on the day of surgery
Cataract Surgery Procedure:
Cataract surgery involves the following steps:
- Initially, doctors use eye drops that dilate your pupils.
- Then the eye area is washed and cleaned.
- The doctor then injects the anesthetic into your eye tissue or anesthesia can also be given in the form of drops.
- The eyelid holder is used to keep your eyelids open and in place.
There are two ways to remove cataracts from your eyes:
In the process of phacoemulsification:
- With a scalpel or a right laser, the doctor cuts less than 1-4 mm along the cornea.
- Through the lens capsule, an incision is made through which a small probe is inserted, which emits ultrasonic waves. Ultrasonic waves break the cloudy lens into pieces.
- The doctor suctions the fragment through the incision.
- He then injects a small artificial intraocular lens made of plastic, silicone or acrylic with an incision.
- Inside, the artificial lens opens automatically and takes the position of a natural lens.
- After the artificial lens inserted in the eye, the process is complete.
- No stitches are needed because the incisions are tiny.
These artificial lenses almost always remain for the rest of a person’s life.
In the extracapsular method of cataract surgery:
- The doctor makes a reasonably large incision (10-12 mm) on the side of the cornea.
- Through the incision, the doctor removes all the cloudy lenses as a single piece.
- He then inserted the artificial lens through the incision to replace the natural lens.
- After inserting the artificial lens, the doctor stitches because of a large incision. This stitch does not need to remove; they dissolve itself.
Recovery time for extracapsular cataract surgery is long, as compared to phacoemulsification, because of a large incision.
Once the cataract is extracted through phacoemulsification or extracapsular extraction, the artificial lens will be implanted in an empty lens capsule.
The types of used artificial lenses available include:
- Monofocal lenses
- Fixed Focus Monofocal IOLs
- Accommodating Monofocal IOLs
- Astigmatic (toric) IOLs
- Multifocal lenses
Which type of intraocular lens is best for you depends on your current vision and your current lifestyle requirements. The surgeon may suggest you with the best cataract that is the most suitable lens to the implant.
Post Operative Care :
- Vision will look blurred in the first few days
- It is recommended not to go out a few days after surgery to avoid sudden injury and direct sunlight.
- You should always wear sunglasses at home, so your eyes feel less sensitive to light
- It is common to experience slight eye irritation and eye discharge after surgery.
- You should not rub your eyes or spray water for at least two weeks after surgery
- Don’t use facial cleansers or soap on your face for two weeks after surgery; you can use baby wipes to clean your face
- Don’t wash your hair in the first week after surgery. If you want to wash your hair next week, make sure the shampoo does not enter your eyes
- Avoid bathing
- During sleep, use glasses that protect your eyes if you accidentally try to rub them while you are at sleep.
- We recommend that you avoid intensive activities or exercises such as gardening, weight lifting, jogging, swimming, yoga, or aerobics.
- Your doctor will also advise you not to bend for several days to avoid additional eye strain
- You should not drive until you are sure that your vision is clear and stable.
- Most people need glasses at least occasionally after cataract surgery. Your doctor after surgery will tell you if your eyes healed completely if so you will receive the final prescription for a pair of glasses.
After a few days, most of the discomfort will go away. Total healing often occurs within eight weeks. If you experience any of the following symptoms, contact doctors immediately :
- Persistent pain despite the use of over-the-counter pain medications
- Vision loss
