Advanced Cataract Surgery

The formation of cataracts very commonly accompanies the aging process and often interferes with or prevents clear sight.

A cataract is a clouding of the eye’s natural lens that occurs in a slow and progressive manner. The cause is a change in the proteins of the lens resulting in it becoming less translucent. A cataract progressively interferes with light passing through the eye, with the unfortunate consequence of blurred or fuzzy vision. For the vast majority of cases, surgery is the only cure.

Cataract surgery has come a very long way over many decades and today, cataract surgery is typically performed with just a small incision and high-frequency ultrasound called phacoemulsification.

Phacoemulsification breaks up the cloudy lens material and a micro-vacuum is used to remove it from the eye. Then, a clear lens (artificial implant) of appropriate power is placed inside the eye for the purpose of providing focusing power. Dr. Singh prefers to utilize no-stitch cataract surgery whenever possible, but it is not always possible.

The Procedure

To commence the procedure, the pupil is dilated. Next, the surgical area is made ready by applying a sterile cleanser. A topical anesthetic administration to the surface of the eye follows. Then, an incision of generally 2.5 to 3 millimeters in length is created at the junction of the cornea (the clear front of the eye) and the sclera (the white part of the eye).


After making this incision, another dose of anesthetic may be administered inside the eye. The front part of the lens envelope (lens capsule) is carefully opened, exposing the cataract. Using an ultrasonic needle, Dr. Singh breaks up the cloudy cataract material while simultaneously using a micro-vacuum to remove the cataract particles from the eye.

With no more cataract or cataract particles in the eye, a soft and folded intraocular lens is inserted through the original incision and placed inside the lens capsule. This commonly referred to as an IOL Implant.

Once the lens is properly centered, Dr. Singh verifies that the eye is at a normal pressure as well as watertight. In the majority of circumstances, sutures (stitches) are not required to help keep the incision sealed. The actual construction of the minute surgical opening is made in a way that allows it to seal itself, thereby avoiding the need for sutures.

Conclusion is brought to the procedure by the application of an antibiotic medicine to the eye. Dr. Singh may recommend a protective eye shield.

Recovery from cataract surgery is ordinarily very rapid and painless. Most patients achieve noticeably better vision within several days of the procedure. Patients are prescribed antibiotic and anti-inflammatory eye drops for the first few weeks following surgery. This is a very simple yet very important responsibility for the patient.

Strenuous activity needs to be avoided for at least the first week after surgery; and cataract surgery patients also need to refrain from rubbing their eyes. Glasses may be required after cataract surgery to achieve the best vision possible. Typically, they will be prescribed three to four weeks post-surgery. Both eyes may be scheduled to have surgery within a period of a few weeks; and, in such cases, glasses will be prescribed once the full recovery of the second eye is confirmed.

Dr. Singh will be happy to assess how the cataract is affecting your lifestyle in combination with the clinical examination to determine if cataract surgery is right for you.

Monofocal Lens Implants

Monofocal lens implants were the only option available for cataract surgery during the first 30 years of the surgery’s history.

A monofocal lens implant provides excellent vision, but only at one distance. So, patients who choose to have monofocal lens implants will be able to see well at a distance after surgery, but will still need to use reading glasses as this particular type of lens will not correct intermediate (arm’s length) in about 70% of all cases.

Astigmatic Correcting Implants

Astigmatism is refractive error which causes people to be unable to see objects clearly from a distance or up close.

If you have been diagnosed with both astigmatism cataracts, there is a premium lens option for you following cataract surgery.

In the past, there was no option to have astigmatism correction built into the lens. Cataract surgeons only had the option of performing refractive surgery or LASIK after the implant of the IOL.

Now, Dr. Singh has newer technology through which he can offer you a special intraocular lens (IOL) implant for astigmatism correction. The cataracts and astigmatisms can be corrected all in one surgery.


Multifocal IOL

In advanced cataract surgery, the cloudy natural lens is removed from the eye and a permanent intraocular lens (IOL) implant replaces the natural lens. Thus, focusing power is restored.

Dr. Singh utilizes the most technologically advanced products available which are designed to reduce spherical aberrations, increase contrast sensitivity, and improve functional vision (at near, far, and intermediate distances). These products offer enhanced clarity and improved image quality.
