Understanding Cataract with Dr. Niteen Dedhia
The most common cause of cataract is age. Some of the other cause of cataract are diabetes, Injuries to eye and thyroid disorder.
Symptoms of Cataract
The Symptoms related to Cataract are the patients normally see the blurred vision; he has difficulty in Night Driving and also sometimes as Double vision. All this condition can occur after the age of 40 and so we advise most of the people to undergo or to have an eye examination with an Eye Doctor as soon as they have problem-related to a vision problem.
Treatment of Cataract
Cataract surgery evolved in the last 2 to 3 decades. Initially, when we used to perform cataract operation the whole cataract was removed from within the eye through a very large incision which is almost about 8 to 10 mm inside. After removing the cataract, we were taking stitches to close the incision and a riches lens was implanted in India. Now the technology as evolved and performed the cataract operation just 2 mm incision and this incision is also made either with laser or with the diamond instrument. Once the cataract is emulsified or liquefied inside the eyes. It is sub out and it becomes almost like water after removing this cataract the lens implanted in the eye from this lens is special foldable lens and it passes through the same 2-mile meter incision and it unfolds him inside the eye. There are different types of the lens which are available: They could either unifocal lens which allows you to see very fear very clearly and for reading you have to read glasses. The Other lens which is available is the multifocal lens and did in the multifocal lens we have a bifocal and trifocal lens and they give you good crystal vision work for far, near as well intermediate vision.
Misconception of Cataract
There are lots of Misconception of about Cataract operation previously patients they use to undergo cataract operation only when cataract was right or when it is mutual but now a day’s cataract operation can be done even if its just 10 percent or 20 percent or when the patient starts having Difficulty in Night driving, or safe thing. The kind of number you get after the cataract operation is also very mineable Because we are able to remove the power of the glasses once cataract is implanted This is because cataract operation as it is done the lens which is implanted is of specific power that power point size the glasses power so its help one to remove the glasses look booth for far as well as near if we are implanting the lens which is the multifocal lens.

The opacification of the normal transparent lens is called cataract. The Latin word “Cataracta” means Waterfall – imagine trying to see through a sheet of falling water or through a frosted or fogged up window.
History
Eye with Normal Lens
Eye with Cataract
The earliest surgical treatment for cataract began in India and was called couching. In this procedure the sclera is incised and the lens is dislocated backward into the vitreous and displaced out of the optical axis. This procedure was performed for more than 2000 years until mid-eighteenth century. Great progress in cataract surgery has been made in recent years with the introduction of microsurgical instruments, microscope & modern surgical techniques like phacoemulsification
Lens: The lens consists of the
Capsule
Cortex
Nucleus
The primary function of the lens is to focus light on the retina, while remaining transparent. This transparency depends on maintenance of structural (anatomic) & functional (physiologic) integrity of its cells.
The lens is 66% water, the least hydrated organ of the body, the remaining bulk is composed mainly of protein. It is devoid of any blood supply and derives its nourishment from the surrounding fluid of the eye i.e. aqueous & vitreous.
Age related or senile: Occurs as a result of natural ageing process of lens fibers, which become opaque over a period of time.
Traumatic Cataract: Develops as a result of injury to the eye.
Metabolic Cataract: Develops as a result of defect in body metabolism – Diabetes- Calcium disorders.
Toxic Cataract: Certain Toxic Substances or Drugs can lead to cataract if taken for a long time due to any reason. Eg. Steroids Miotics, Chlorpromazine, etc.
Secondary Cataract: develops as a result of some other primary eye disease such as chronic inflammation or glaucoma.
It varies from person to person but as a general rule, most cataracts develop slowly over a period of time. A cataract can take months or even years to reach a point where is adversely affects vision.
One may not be aware that a cataract is developing if the size and location of the cloudy areas in the lens are not in the Central pupillary area. As the cataract progresses, there is deterioration of distance and reading vision. One may experience hazy and blurred vision. Double vision may also occur when a cataract is beginning to form.
Eye with Cataract
The eye may also be more sensitive to light and glare, making night driving difficult. There may be a need to change the glass prescription in the early stages which may help temporally. As the Cataract develops, stronger glasses would no longer improve the vision. This can lead to imbalance between the two eyes, which may cause headache. One may also experience Poor night vision, poor depth perception e.g. difficulty in getting downstairs.

Causes of cataract
Age-related cataract
The cataract occurs as a result of the natural aging process of lens fibres which become opaque over a period of time.
Traumatic cataract
Due to a direct penetrating injury.
Concussion- Electric shock and lightning.
Ionizing radiation done as treatment for ocular tumors.
Surgical trauma
Metabolic cataract: Defect in body metabolism
Diabetes
Galactosaemia -inborn error of metabolism
Calcium disorders
Steroid-induced cataract
This occurs as a result of excess intake of oral steroid or putting steroid drops in the eye.
Secondary cataract
Here, cataract develops as a result of some other primary ocular disease such as chronic eye inflammation or glaucoma.
History of Cataract treatment
The earliest surgery treatment was started in India, by Maharshi Sushruta. It was known as ‘couching’, where the cataractous lens was dislocated backward into the bottom of the eye and out of visual axis.
This procedure was performed for more than two thousand years until the mid-eighteenth century. Great progress in cataract surgery has been made in recent years with the introduction of micro-surgical instruments, microscope and modern surgical techniques like phacoemulsification, which has made couching obsolete.
In the early stages of cataract development, all that is needed to correct your vision with glasses is a change in prescription. As the cataract develops and begins to affect your lifestyle, it needs to be removed. Cataract surgery, the most commonly performed operation, is safe and effective in 95% patients with enhancement in vision.
Methods of evaluation of cataracts:
Visual acuity: Checking vision of both eyes unaided and aided with glasses and pin-hole vision to know the improvement as well as to get the general idea about the macular function of the eyes. This will help in prognostic evaluation of visual recovery after cataract surgery.
Intra ocular pressure: If intra-ocular pressure increases as a secondary to cataract surgery is needed to prevent further complications.
Slit-lamp examination: To know the type of cataract along with its opacity, morphology and etiology or any associated ocular pathology.
Direct and indirect ophthalmoscopy: for complete retinal evaluation. Dense cataract will prevent retinal evaluation and such cases need B-scan for retinal evaluation.
A-scan biometry: To calculate the AL and IOL power for implantation in cases of mature cataract the posterior segment of the eye is evaluated.
Optical biometry: this is an advanced non contact method to measure IOL power. It is patient friendly and highly precise
Treatment Options Available For Cataract
Extra Capsular Cataract Extraction (ECCE): is a conventional technique.
ECCE requires an incision of 10-12mm
The doctor removes the clouded lens in one piece.
Multiple stitches are required.
Doctor implants a non-foldable lens
Phacoemulsification – A Micro Incision Cataract Surgery
Cataract Surgery Explain By Dr Niteen Dedhia
Phacoemulsification is latest technology in Cataract surgery. It is a micro-incisional stitch less operation where cataract is emulsified by ultra sound energy, liquefied & sucked through the phacoemulsifier probe. A foldable intra- ocular lens is then implanted in the eye permanently.
Vision restoration is possible in a short period of time & is least traumatic with early rehabilitation & recuperation.
Advantages
It is Stitchless. Hence healing is very fast.
It is done under Topical anaesthesia (by putting drops.) So no need to patch the eye except in special circumstances
Vision correction for far & near is possible
Patient can get back to work in the shortest possible time
During cataract surgery, the natural lens of the eye that has turned opaque is removed, resulting in loss of focusing power of the eye. This situation would be parallel to clicking a photograph without a camera lens–the picture would be extremely blurred. When the natural lens of the eye is removed an artificial implant is placed in the eye.
Intraocular Lens
An intraocular lens (IOL) implant is a synthetic, artificial lens placed inside the eye that replaces the natural lens which is surgically removed usually as a part of cataract surgery.
Monofocal intraocular lens can be used to give clear point focus either at a distance or close up, but one can choose only one focal point.
Multifocal IOLs are popular as they allow correction of vision for both far & near distance.
Trifocal IOLs provides excellent vision not only for near and far, but also for intermediate distances, especially for people who have routine usage of computers.
Apodized Diffractive Multifocal IOL
Gradual diffractive steps on the IOL implant that create a smooth transition between focal points. The IOL bends incoming light to the multiple focal points to increase vision in differing light situations.
Accomodative IOL
Crystalens and Trulign Toric currently are the only US-FDA -approved intraocular lenses (IOLs) that use a method called accommodation, enabling sharper vision at multiple distances for people who have undergone cataract surgery.
An accommodating IOL shifts position with the action of eye muscles and movement to improve eyesight.
Toric IOL for astigmatism
This is a monofocal IOL with astigmatism correction built into the lens.
Astigmatism: This eye condition distorts or blurs the ability to see both near and distant objects. With astigmatism the cornea (the clear front window of the eye) is not round and smooth (like a basketball), but instead is curved like a football. People with significant degrees of astigmatism are usually most satisfied with toric IOLs.
People who want to reduce (or possibly eliminate) the need for eyeglasses may opt for an additional treatment called limbal relaxing incisions, which may be done at the same time as cataract surgery or separately. These small incisions allow the cornea’s shape to be rounder or more symmetrical.
Protective IOL filters
IOLs include filters to protect the eye’s retina from exposure to UV and other potentially damaging light radiation. The eye doctor selects the filters that will provide appropriate protection for the patient’s specific needs.
Other important cataract lens replacement considerations
In some cases, after healing completely from the cataract lens surgery, some people may need further correction to achieve the best vision possible. Their ophthalmologist may recommend additional surgery to exchange an IOL for another type, implant an additional IOL, or make limbal relaxing incisions in the cornea. Other laser refractive surgery may be recommended in some cases.
People who have had refractive surgery such as LASIK need to be carefully evaluated before getting IOLs because the ability to calculate the correct IOL prescription may be affected by the previous refractive surgery.
Refractive Laser-Assisted Cataract Surgery (ReLACS)
Laser-assisted cataract surgery is now available to our cataract patients.
The Femtosecond Laser applies laser energy in an extremely short period of time, one trillionth of a second, so no significant heat is generated (therefore, it is a “cool” laser). The laser, guided by an advanced imaging system known as OCT, creates precise incisions, automating steps of cataract surgery that have traditionally been done manually with a surgical blade. The laser can also make corneal incisions to treat astigmatism. The computer-driven incisions are more precise and reproducible than what can be done manually by hand.
In laser cataract surgery, an advanced Femtosecond Laser replaces or assists use of a hand-held surgical tool for the following steps in cataract surgery:
The corneal incision
The anterior capsulotomy
Lens and cataract fragmentation
Use of a laser can improve the precision, accuracy and reproducibility of each of these steps, potentially reducing risks and improving visual outcomes of cataract surgery.
In laser cataract surgery, the surgeon creates a precise surgical plan for the corneal incision with a sophisticated 3-D image of the eye called an OCT (optical coherence tomography).
An incision with a specific location, depth and length in all planes with the OCT image and a femtosecond laser can be performed exactly without the variable of surgeon experience.
