Facility - Cataract





This department is set up to diagnose and treat patients with age related and other types of complex cataract.  CATARACT surgery is done by Phacoemulsification with Unifocal, Foldable and Multifocal Intra Ocular Lens. In addition to this the hospital is a specialty center for GLAUCOMA and SQUINT.

This department is equipped with:

  • Ophthalmic Examination Units

  • Slit Lamp Bio-Microscopes

  • Autorefractometer

  • Lensometer

  • Direct Ophthalmoscope

  • YAG Laser

  • Gonioscopy

  • Low Visual Aids

  • Contact Lens Clinic and Spectacle Counter

What is Cataract?

Cataract is described as a condition in which the normal human lens of the eye turns cloudy and later becomes opaque. The normal lens is transparent and allows light to reach the retina. When it becomes opaque (Cataract) light does not reach the retina and the patient is unable to see clearly.

Why does Cataract form?

Cataract is the most common cause of blindness in our country. The causes of formation of cataract are not fully known.

  • It is an aging problem.

  • Ultraviolet light exposure.

  • Deficiency of protein and vitamins.

  • Exposure to steroids and various other medications,

Apart from cataract in old age cataract can also occur in children or adolescents. Injuries can produce cataracts in all age groups. Patients with diabetes mellitus develop cataracts earlier than a normal person.

Symptoms

  • Blurring of image in bright light.

  • Double images.

  • Image distortion. `

  • Unequal vision in eyes.

  • Frequent change of glass

Treatment of Cataract

Till date there is no drug, which has been proven to cure cataract. The only treatment available is surgical removal of cataract.

When does cataract require removal?

Apart from the mature cataracts, even immature cataracts need to be removed if it hampers with the patients visual requirements. There is no necessity to wait for the cataract to ripen as in earlier times.

At PRADNYA NETHRALAYA we are performing the latest techniques for cataract removal. We remove the cataract through a micro incision by an ultrasonic aspiration technique called Phacoemulsification. Almost all the patients are implanted with intraocular lenses. The success rate after surgery is close to 99.5%.


Phacoemulsification

This technique is a marvel of modern medical technology and is performed as an outpatient procedure. In this procedure the clouded lens is fragmented with ultrasound vibrations, into tiny pieces and removed through a small self sealing 1.8 mm TO 2.8 mm opening There are no sutures.

The surgery is

  • Stitch less

  • Bloodless

  • Painless

  • More controlled


  • It helps Patient‘s

  • Early rehabilitation

  • Less post operative discomfort

  • Less induced astigmatism

  • Minimum post operative restriction

  • More satisfied general condition


  • Except in cases of very hard Cataracts, Phacoemulsification can be done in all other cases


    FOLDABLE INTRAOCULAR LENS


    Cataract extraction by phacoemulsification through a very small incision and foldable/injectable lens implanted through it. It is a precision technique performed under an operating microscope.


    The lens is injected through the small opening and it opens inside the eye


    ADVANTAGES


    Wound healing is faster


    Wound stability is better since the entire surgery is done through a small key hole


    Induced astigmatism is minimal


    Decreased glare


    TYPES OF LENS USED


    FOLDABLE HYDROPHILIC LENS


    These quality lenses are time tested


    Can be injected through a small opening


    Incidence of posterior capsular opacification is high.


    FOLDABLE HYDROPHOBIC LENS


    These are most biocompatible and cause least incidence of posterior capsular opacification.


    These are well recommended, specifically for the Patients with,


    Diabetes


    Traumatic cataract and


    Children with cataract


    ASPHERIC MONOFOCAL LENS


    Regular spherical intraocular lens have the inherent limitation of refracting multiple focal points due to inherent change in curvature of the lens .This affects the quality of vision.


    Aspheric monofocal lens eliminates this limitation and enhances the quality of vision. The lens gives the best quality of vision after cataract surgery by eliminating the spherical aberrations as in the case of High definition TV.


    MULTIFOCAL INTRAOCULAR LENS


    Most intraocular lens takes care of distance vision. For near vision or for computer work one needs to wear correction glasses. However, multifocal intraocular lens takes care of distant, intermediate and near vision and therefore, the persons can perform all their activities without glasses.


    TORIC INTRAOCUALR LENS


    Sometimes the surface of the cornea may be curved more in one direction than in the other, called corneal astigmatism .Persons with corneal astigmatism have blurred or distorted vision. In these cases, after cataract surgery they may not regain high-quality vision unless the astigmatism is also corrected
    This astigmatism can be corrected by implanting TORIC intraocular lens
