What is cataract?
It is loss of clarity of the natural lens, which prevents light rays from reaching the retina. It might vary from slight grayish discolouration of lens to pearly white or brownish-black coloured lens depending on the stage and type of cataract.
- In early cases, a simple change in spectacle power may help. However quality of vision may be affected, and can be noticed easily if the cataract is more in one eye.
- As the cataract progresses, vision drops even with spectacles, till finally only the perception of light remains.
What are the causes of cataract?
Ageing is the most common cause of cataract. Every person gets it sooner or later, especially people over 60 years of age. Occasionally it can start at a younger age and rarely it may be present even at birth. Other causes include diabetes, eye injury, use of certain medications, and secondary to other eye diseases such as uveitis and glaucoma.
What are the symptoms of cataract?
- The most common symptom blurring of vision, which is painless and gradually worsens. Other symptoms include double vision or seeing multiple images, trouble with seeing in dim light and sometimes in excessive sunlight, and becoming sensitive to glare, making night driving difficult. Difficulty in distance vision and in reading are also experienced. Here at Laxmi Eye Hospital we are specialized Cataract Treatment in Navi Mumbai.

At Laxmi, we have always been at the forefront of embracing new technologies which increase our accuracy and precision, improve safety, or enhance patient comfort. Let’s take a closer look at some of the sophisticated equipment in our armamentarium.
Once cataract is diagnosed, preoperative tests and evaluation are done to calculate the power as well as determine the appropriate type of the lens to be implanted. This technology of using the appropriate IOL based on individual eye parameters is referred to as Customised Cataract Surgery.
Biometry (IOL power calculation) is done by trained personnel and every effort is made to ensure accurate results. It involves measurement of the eyeball length and corneal power.
Pentacam (Oculyzer from Alcon)– This is based on Scheimpflug camera wherein the corneal power is measured at multiple points. These measurements are based on elevation from a reference sphere – a form of elevation-based topography.
The Pentacam can also accurately measure thickness of the cornea at various locations. This helps in assessing the corneal cylinder (astigmatism) accurately for planning toric IOLs as well as for planning limbal relaxing incisions for correction of astigmatism during surgery.
The Pentacam helps us to manage complex cases such as patients coming for cataract surgery after having undergone refractive surgery (for example LASIK or PRK) or those with Keratoconus.
iTrace – This unique machine works on the principle of ray tracing technology. Visual problems can arise from loss of clarity in 2 important structures in the eye namely cornea and lens. iTrace can quantitatively estimate the visual loss due to each component and can reasonably predict the vision after cataract surgery.
It can exactly measure the spherical aberration of the eye and helps in the selection of an appropriate aspheric IOL. The iTrace also measures various visual angles of the eye (angle alpha and angle kappa) which are useful in selection of premium IOLs like multifocal, trifocal and toric IOLs.
IOL Master – This works on the principle of partial coherence laser interferometry. Here the length of the eye is measured using laser, and hence is extremely accurate for calculating IOL power calculation. All the measurements are taken without touching the patient’s eye. It is an extremely fast machine which can take hundreds of readings within minutes.
Let’s now look at some of the equipment that is used during the cataract surgery.
Alcon Infiniti Phaco Machine – This is an advanced Phacoemulsification system, which incorporates conventional longitudinal phaco technology with Ozil technology. In Ozil technology, the tip of the phaco probe moves horizontally as well as longitudinally. This tremendously improves the efficiency of the machine to emulsify the cataract without damaging adjacent eye structures. Advanced fluidics sensors in the machine further increase the safety of the system during surgery.
Zeiss Visu 200 Microscope – This is a top-end microscope backed by German engineering and the finest optics from Carl Zeiss. It provides best visualisation of the minute structures inside the eye during surgery.
Positive Pressure Ventilation System – The operation theatre is equipped with a positive pressure ventilation system, which prevents contaminated air entering the operation theatre. It is equipped with HEPA filters, which exclude all pathogenic microorganisms which can cause infection.
- Surgery can be performed manually through 5- 6 mm wound called SICS (Small Inscision Cataract Surgery).
- Phacoemulsification is at present the universally accepted standard-of-care for cataract surgery.
- Ultrasound energy is used in phacoemulsification to break up the cataract (emulsify) into microscopic fragments which can be sucked out of the eye.
What is MICS?
- The surgical wounds have progressively become smaller and now the latest technique is “Micro-coaxial Phacoemulsification” or MICS.
- MICS is phacoemulsification of the cataract through a wound of 2.2 mm or less, with implantation of an intra-ocular lens through the same wound.
- Wound healing and refractive stabilization is faster in MICS than in traditional phaco.
- Furthermore these lenses are preloaded by the manufacturer into the injector. Thus they can be directly injected into the eye without touching the lens by any instruments.
Is there a choice in the type of lens to be implanted in the eye?
The majority of the IOLs implanted are mono-focal. They can focus light rays from one particular distance only. Normally distance objects are clear and one needs glasses for reading.
Intra ocular lens can be rigid or foldable. The advantage of foldable lenses is that it can be inserted through a smaller wound.
Monofocal Aspheric IOLs
These IOLs additionally correct ‘higher order aberrations’ (especially spherical aberration), which cannot be otherwise corrected by spectacles. This improves the quality of vision and clarity especially in dim light condition.
Multifocal lenses are specially engineered and have different segments built onto the same lens. These segments focus light from both distant as well as near objects, allowing spectacle freedom for most activities.
Traditionally used monofocal IOLs correct only the spherical refractive error. Patients with pre existing astigmatism will need spectacle correction for distance vision and near. Toric IOLs eliminates the need of glasses for distance.
Recently multifocal IOLs have also been introduced with this option, thus correcting for distance, near and cylindrical error.
A limitation of standard multifocal IOLs is that they provide good distance and near vision but have a somewhat compromised intermediate vision. This is the distance used for working on computers. Trifocal IOLs provide excellent vision not only for near and far, but also for intermediate distances.
Toric Multifocal IOLs
Astigmatism is a refractive error in which the curvature of the cornea is different in different meridia. The shape is more akin to an American football rather than a regular football. People with astigmatism were earlier not suitable for multifocal IOLs. Now with the introduction of Toric Multifocal IOLs, it is possible to correct this astigmatism and also provide good near vision to this group of people.

Cataract surgery is avoided during episodes of acute illness like fever, infections, cough and cold. Patients with well controlled diabetes and hypertension (blood pressure) can easily undergo cataract surgery. Patients with advances diseases of the heart, lungs, kidney, liver or any other organ need to have a detailed examination and clearance from their respective physicians to undergo surgery.
If I have cataract in both eyes can I have both eyes operated on the same day?
Although both eyes can be operated on the same day, most surgeons prefer to keep a gap of at least a week between the surgeries of the 2 eyes. However, exceptions can be made as per the need of the patient and each individual case.
How long do I have to be in the hospital after the surgery?
Patients typically have to spend only a few hours at the hospital and are allowed to go home in the afternoon.
How long after surgery will I be able to see again?
Every patient and every eye is different, but most patients typically see well enough to drive only a day after surgery. The doctor can tell how quickly he or she expects you to recover.
How many days after the surgery can I return to normal activities?
Most patients can resume basic activities like reading and watching TV the day after surgery, and can usually return to work within two to seven days. It is advisable to avoid any strenuous activity for two or more weeks. Results vary by patients; however, so ask your doctor what’s best for you.
Will I have to wear glasses after cataract surgery?
Usually most of the activities of daily living can be carried out without glasses after cataract surgery. If a Monofocal IOL has been implanted in your eye, you will have excellent distance vision but may need to wear glasses to see fine print in books and papers or to do other activities at near distance. Same is true for Toric Monofocals IOLs. With plain Multifocals and Toric Multifocals a person can lead a more spectacle independent life and is able to perform almost all the tasks of near and distance vision without glasses.
Will I get cataract again after surgery?
Once a cataract has been removed, it cannot return. However, after some time, patients may notice that their vision has once again become blurred. This condition is known as a secondary cataract or posterior capsular opacification (PCO) and can occur after cataract surgery with any type of IOL. It can be easily treated with a simple laser procedure performed in the clinic.
Can the IOL be replaced if it doesn’t work properly?
It’s very unlikely that the implanted IOL won’t function properly. However, it can be replaced with a different one if necessary. Your surgeon will usually take a decision regarding such an exchange if required.
What precautions should I take after surgery?
Refraining from rubbing your eye or engaging in any strenuous activity for a few weeks after surgery and using the eye drops as prescribed usually suffices as precautions after the surgery. However, as each case is different, one should ask the doctor about any additional precautions if required.
Who should I call if I have a problem after surgery?
Consult your doctor immediately if you have any issues, particularly if you experience decreased vision or increased redness and pain. Do not postpone this consultation as it may be sight threatening. Ask your doctor whether there are emergency services available in his clinic if you need to call upon him after office hours.
Cataract Treatment cost in Mumbai.
Now a days with technological advancements, technically there are two types of treatments available for cataract surgery.
1) Bladeless Cataract Treatment
2) Phacoemulsification, commonly termed as Phaco Cataract Surgery.
The difference between these two is in the 1st step of cataract surgery, ie. making an incision, a cut, for phaco process. Bladeless does it with a laser and traditional cataract surgery does it with an advanced micro Keratome blade.
Cataract treatment cost in general depends on selection of lens and the technology used for the surgery. Which may vary from Rs.7000 to Rs.120000 per eye.
