What are the different types of IOLs (Intraocular Lens) used for Cataract Surgery?
Choosing the right intraocular lens (IOLs) for your cataract surgery is extremely important. Typically, the lenses used for cataracts are- posterior chamber lenses (PCIOL). After extraction of your natural lenses, your eye doctor places these on the residual posterior capsule. (which is also the original position of your lens.)
PCIOLs are generally divided into 4 types:
- Monofocal lenses: These allow the patient to see clearly only at a certain distance, either near or far.
- Multifocal lenses: As the name suggests, these correct both- nearby and farby vision at the same time.
- Trifocal lenses: These clear the vision for all nearby, farby, and all the intermediate distances in between.
- Toric lenses: These correct both- the spherical as well as cylindrical power of the eye at all distances.
Which lens is better for you depends directly on your needs, personal choice, and financial budget. You could discuss the same with our ophthalmologists to have a clearer idea and decide better.
How to prepare for Cataract Surgery?
The preparation for cataract surgeries is simple. Your doctor would require you to:
- Take the prescribed eye drops or medications a night before the surgery.
- Avoid eating or drinking anything post-midnight.
- Additionally, if you have a habit of smoking, you would be asked to limit its usage for at least one month before to make sure smoking doesn’t impair your healing abilities.
Recovery After Cataract Surgery
While you will be able to retrieve more than 90% of your vision on the same day, a complete recovery may take a little over or around a month. For the first week, you would be given an eyeglass or an eye shield to protect your eyes from any damage or external pressure.
During this time, we advise the following precautions:
- Do not lift any weight heavier than 3-4 kgs.
- Do not bend over.
- Avoid spicy or bloating food.
- Avoid straining (even during bowel movements).

What are the different types of Cataract Surgery?
All types of cataract surgery involve the replacement of the natural lens with an artificial implant, which is known as an intraocular lens (IOL). In Patna and every other city across India, the following techniques are available to perform cataract operations:
- Phacoemulsification Cataract Surgery- It is one of the most common techniques used for cataract treatment. During phacoemulsification, the surgeon makes an incision around 2 to 3 mm with the help of an ultrasonic probe. The probe breaks up the cataract using vibration and removes the fragments with a suction device. Then a foldable lens is inserted into the eye through the incision.
- Manual Extracapsular Cataract Surgery (MECS)- MECS is a technique that involves making a large incision, around 9 to 13mm long to remove the clouded eye lens and replace it with the IOL.
- Manual Small Incision Cataract Surgery (MSICS)- It is a variation of MECS in which a smaller V-shaped incision is made in the eye. The incision becomes wider as it reaches the lens. While the outer incision is around 6.5 mm, the inner incision is around 11 mm.
- Micro Incision Cataract Surgery (MICS)- As the name suggests, micro-incision cataract surgery is done through a 1.8 mm incision which is even smaller than small incision cataract surgery (MSICS). The rest of the procedure stays the same. The clouded lens is removed and replaced with an artificial lens.
- Femtosecond Laser-assisted Cataract Surgery (FLACS)- It is the latest technique to perform cataract surgery. A femtosecond laser is used to make the incision and the laser further divides and softens the cataract. Due to this, a minimal amount of phacoemulsification energy is required to remove the clouded lens.
- Intracapsular Cataract Surgery- This type of cataract surgery involves the removal of the entire lens and the lens capsule from the eye. It requires a big incision and has many risks and complications. Therefore, it is rarely performed nowadays.
Out of all these types of cataract surgery, each has its own set of advantages and disadvantages. Not to mention that each technique has some side effects and chances of complications. Therefore, when you consult a cataract doctor, he/she diagnoses the condition thoroughly and then suggests the appropriate technique which is safe for the patient.
How to choose the best cataract lens for you?
The best thing about cataract surgery is that once the lens is replaced, the results are permanent. And there are different types of lenses for cataract surgery, each of which has unique benefits. These lenses are widely known as intraocular lenses and are classified into the following types:
- Standard Lens (Monofocal)- This type of lens addresses the vision problems at a specific distance, i.e., either nearby vision or distant vision. You can choose between the two depending on the activities you perform on a regular basis. Monofocal lenses are usually spherical, i.e., the surface is uniformly curved, allowing the patient to see clearly at one distance only.
- Multifocal IOLs- These lenses can help the patient to see distant and nearby objects clearly at the same time. These are considered premium lenses because they have both multifocal and accommodative properties that allow the patient to see at different ranges at the same time. Multifocal lenses are aspherical, therefore, they can correct presbyopia and astigmatism at the same time.
- Toric Lens (IOLs)- This type of lens is specially made to correct astigmatism in cataract patients. There is a special type of toric lens as well that provides extended depth-of-focus. These lenses are slightly more expensive than other types as well.
- Monovision Lens- People often confuse monovision lenses with monofocal lenses. There is a significant difference between these two. While a monofocal lens provides clear vision at a distance only, a monovision lens is implanted in both eyes to correct vision problems. An intraocular lens is implanted in one eye that provides nearby vision and another lens is implanted in the other eye that provides distance vision.
The doctor does an accurate diagnosis to determine the appropriate power of the IOL and provide desired results to the patient in terms of refractive outcomes after the surgery. You will have a detailed discussion with the doctor about these types of lenses for cataract surgery before proceeding with the treatment. The specialist will also provide you with information about the best cataract lens brands in India, such as Bausch & Lomb, Freshlook, Acuvue, Alcon, Johnson & Johnson, Zeiss, etc. to make the decision.
