Conventional cataract surgery demands a large incision followed by suturing leading to slow visual recovery. The new technique of Phacoemulsification being sutureless brings down the incision size to 2.8mm leading to immediate visual recovery. Use of foldable and multifocal IOL's with aid of micro incision cataract surgery has further improved the visual recovery time, as well as the patients comfort level during the post operative period. The surgery is done under topical anesthesia with no injection and no suture technique.
M.N. Eye hospital is equipped with ultra modern equipments and highly experienced surgeons to provide best possible eye care to its patients.
Apart from ultramodern facilities for surgery , M N eye hospital also provide wide range of lenses like Multifocal IOL's, Toric IOL's, and various other Premium IOL ‘s for the patient to choose from.
Description
Cataract is the clouding of the natural crystalline lens and typically occurs because of ageing, although other reasons may be prolonged use of steroids, exposure to ultra violet and associated health problems like diabetes and eye injuries. Surgery is the only known effective treatment for cataract removal. Cataract surgeries are performed with removal of the cloudy natural lens and replacing it with an Intra Ocular Lens (IOL). We at M.N. Eye Hospitals, Micro Incision Cataract surgeries are performed under Topical anesthesia (without Injection) and a foldable IOL is inserted.
Types of cataracts
Senile cataract
Senile cataract is by far the most common type of cataract. Senile cataract can be compared to getting wrinkles and turning grey. Due to an aging population, this type of cataract is on the increase.
Congenital cataracts
Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born, or they may develop during childhood.
Secondary cataracts
Medical conditions like diabetes, or exposure to toxic substances, certain drugs, ultraviolet light, or radiation.
Traumatic cataracts:
These form after injury to the eye.
Other factors that can increase a person’s risk of developing cataracts include cigarette smoke, air pollution, and heavy alcohol consumption.
A-L Scan (Nidek):
This is the World’s best machine for calculation of IOL power. It is a non-contact technique during which the patient is seated comfortable with his/her chin on a chin rest. The machine automatically directs a light into the eye and does calculations without touching the eye. The patient does not feel anything and the machine does its work in few seconds.
B-Scan:
Also called as Ultrasound Scan of the eye is performed to assess the posterior segment (the fundus, retina, optic nerve) of the eye. B-scan is a safe and non-invasive procedure.
A-Scan
A-scan or Biometry calculates the total length of the eye and IOL power of the eye. The readings of this machine are very accurate. The cornea is gentle touched with pain/discomfort to the patient. In cases of premium IOLs, refractive IOL and TORIC IOL and post-refractive surgery IOL calculations, IOL Master is used.
Specular Microscopy
With the help of this machine, the health of the cornea (anterior surface of eye) is evaluated. The most important part of the cornea is the most inner layer called as the endothelium. Specular Microscopy is performed before all surgical procedures for maximizing safety of the cornea. It also helps during corneal transplantation procedures.
OPERATING Machines
Lumera zeiss
With OPMI LUMERA 700, even the finest anatomical details are clearly visible, and the red reflex is high in contrast and stable.This sophisticated surgical microscope ensures only the best results, so procedure times are shorter and patient throughput is higher.
B&L Stellaris 1.8MM MICS
- It allows surgeons a platform for the smallest incisions for both retinal and cataract surgeries. It is capable of 1.8 mm MICS phacoemulsification as well as a complement with Bausch + Lomb's existing proprietary 25-gauge system of instruments for retinal surgery, along with standard 23- and 20-gauge instruments.
- It has light-weight, ultrahigh-speed vitrectomy probes for conventional and transconjunctival vitrectomy (TSV).
Oertly OS3
The OS3 is the world’s leading combined system for cataract and vitrectomy surgery. It is technicially advanced, proven and is the cutting-edge of technology. The OS3 meets all surgical challenges thanks to its design concept being well-thought-out from the start.

Why does cataract develop?
Cataract is an age related change in the lens of human eye. Certain diseases and medications too have the capability to induce cataract formation. The human lens is the only structure in the body that continuously keeps growing through out life. The newly formed lens fibers are laid around the old fibers and thus lead to thickening (sclerosis) of the lens. A sclerosed lens loses its capability to converge light rays on the retina. Light rays get scattered and thus cause a blurred vision to the patient. This is when the patient presents to the doctor.
What are the treatment options?
The treatment of cataract involves a surgery called PHACO-EMULSIFICATION with INTRA OCULAR LENS implantation. The phaco procedure is the most recent technique of cataract surgery that involves small incisions in the range of 1.8 to 2.8mm and the cataractous lens emulsified with ultra sound inside the eye. A foldable intra ocular lens can be place through this incision thus helping the patient attain better vision, faster recovery and early return to routine activities.
What are the pre op tests up to be done?
Once selected for cataract surgery and after fixing on the type of surgery and details of the IOL, few pre op investigations need to be done. These tests are mainly for two purposes.
- For finding the power of the lens to be placed in the eye.
- For evaluating the fitness for the surgery.
What will be the anaesthesia?
Most of the cases now are done with topical anesthesia. Drops applied to the eye and surgery will be done. NO MORE PAINFUL INJECTIONS IN THE EYE!!
This said though, if the cataract is hard in nature or if the surgeon on table feels anesthetic injection will be needed, injection will be given!
Post operative period:
The patient can get admitted on the day of surgery and return home the same day evening. Advice on eye drops applying will be given and the patient must review with the ophthalmologist on a weekly basis or as per the advice of the ophthalmologist.
When can the next eye be operated?
With the phaco, technique, now most surgeon prefer to operate both eyes within a gap of 3 days to 1 week. This is usually safe and the period of absence from work has drastically come down.
