CATARACT TREATMENT
IN KAMOTHE
CATARACT TREATMENT
Cataract development is a normal process of ageing.Cataracts can also be present at birth, can occur in children, develop due to eye injuries, certain diseases or medications.
A cataract is a clouding of the eye’s naturally clear lens. When the lens becomes cloudy, light rays cannot pass through it easily and focus on retina to give clear vision and vision becomes blurred.
Cloudy or blurred vision
Frequent changes in eye glasses
Glare
Haloes around lights
Better near vision- second sight
Multiple images
Headlights,lamps or sunlight may appear too bright
- Topical anaesthesia- Anaesthesia (loss of sensation) / analgesia (loss of pain perception) is obtained by putting the eyedrops. The patient can still move his/her eyes, so for this kind of anaesthesia a lot of cooperation is required for the patient to not move the eyes during the middle of the surgery.
- Local anaesthesia- An injection is given around the eye. The patient does not feel the pain and is not able to move his/ her eye till the effect of anaesthesia wears off but is awake during the surgery.
- General anaesthesia- for children and mentally unstable patients.
Types of cataract surgery
- Extracapsular cataract extraction: Incision is around 9mm and sutures are required.
- Manual small incision cataract surgery: Cataract is removed from a 6mm to 7mm incision and usually no sutures are required.
- Phacoemulsification: Cataract is removed from a 2.5mm- 3mm incision.
What is Phacoemulsification?
In this technique ultrasonic waves are used through a small probe which emulsifies the cataract and aspirates it.
Advantages of phacoemulsification:
- Faster healing due to small incision
- Sutures are required hence no foreign body sensation
- Rapid improvement in visual acuity
- Less chances of cylindrical number after the operation.
Intraocular lens implant (IOL)
When the cataractous lens is removed, it has to be replaced by an artificial lens for better vision which can be in the form of spectacles, contact lenses or intraocular lens.Spectacles have their own problems like thick glasses, image magnification and thus poor quality of vision. There is a decrease in the field of vision too.Contact lenses reduce the change in image size but they should be worn and removed everyday and can thus be difficult to handle especially for elderly people.
So instead of extraocular (outside the eye) lenses like spectacles and contact lenses, intraocular lens is implanted inside the eye in the same place after removing the cataractous lens.Lens implants can be non-foldable or foldable. Foldable implants can be implanted through a 2.5mm-3mm incision and they open up inside the eye. There are various types of IOLs available and with the help of your Ophthalmologist one can choose the best suitable IOL.
Risks associated with cataract surgery:
Cataract surgery is usually very safe and has an excellent success rate. But any surgical procedure has its own risks. Patient should be aware that any form of treatment be it a surgery or simple medication for cough or cold has its own side effects and risks. Cataract surgery is no exception. These are some of the complications of cataract surgery:
- Globe perforation or retrobulbar haemorrhage during local anaesthesia
- Reactions to medications
- Posterior capsular rent and inability to implant the intraocular lens
- Nucleus drop and need for an additional procedure by a retinal surgeon
- Refractive surprise- sometimes one can get a high spectacle number of more than 3 dioptres
- Swelling of the retina
- Swelling of cornea
- Dislocation of IOL
- Posterior capsular opacity
