Cataract Surgical procedures and Limitations of Lasik Laser

Impairment or loss of vision can be caused due to metabolic changes of the crystalline len fibers over time lead for the purpose of development of the cataract. Treatment of cataract through cataract surgical procedures is discussed in the first part this blog and limitation of the lasik laser surgical procedures are discussed in second part of this blog.

Cataract Surgical Procedures

Day care and high volume coupled with minimally invasive make the cataract surgical procedures highly effective in restoring vision of patients suffering from impairment of vision due to cataract.

Furthermore, small incision with quick post-op recovery makes the Phacoemulsification as one of the successful cataract surgical procedures for restoration of vision by removal of natural len.

For restoration of the vision, ophthalmologist or eye surgeon make use of two types of cataract surgical procedures. Phacoemulsification (phaco) and extracapsular cataract extraction are different types of surgical procedures for restoration of vision.

As per recent survey, it was reported that the more 90% cataract surgical procedures are successful in restoration of patients, with extremely low complication rate. Strong glare from lights is one of major symptoms of the cataract. Reduced acuity at low light levels is another symptom of symptom.

Cloudy natural cataract lens can be removed through the cataract surgery procedures and are replaced with intraocular lens for the restoration the lens’ transparency. Natural len of the individual suffering from cataract is removed through surgical procedures, for effective restoration of the vision that was hampered due to opacification.  

The implantation of the intraocular lens can be carried by eye surgeons, for restoration of vision. Foldable lenses of 2-3 mm phaco incision are generally implanted or inserted after the Cataract Surgery in Delhi, for restoring the transparency of the len.  Larger extracapsular incision is required for insertion of the non foldable intraocular len after the cataract surgical procedures.  The size of the non foldable lens is about 10-12 mm and often requires stitching for the purpose for ensuring accurate implantation.

Limitation of the Lasik Laser Surgical Procedures

Although lasik laser is associated with high success rate of 92-98% but if carried out by unqualified eye surgeons, the lasik laser surgical procedures are associated with certain limitations. Changes made to the cornea at the lasik laser surgical procedures cannot be reversed. Other limitation of lasik laser surgical procedures is that additional lasik laser surgical procedures can only be performed for further correction of vision. Lasik Laser in Delhi is very technical complex and doctors cut the flap that can affect permanently affects vision. 

Types of Surgeries Performed to Remove Cataract

Cataract is the cloudiness of the lens of the eye. This is due to aging process or due to some physical injury to the eye.  During the cataract surgery, the cloudy lens is removed and is replaced by clear lens, which is a manmade lens.

There are three types of surgerical techniques, by which the cataract is removed. In the extracapsular type, which is also most common technique used in the treatment, the surgeon makes a slit at the side of the cornea and removes the cloudy section of the eye lens.   The rest of the lens is vacuumed. This type of procedure is used in case of advanced cataract.

In Phacoemulsification ,small incision is made in the side of the cornea and then an ultraviolent vibration are send to the eye to break the cloudy lens into small parts. Then these small parts are sucked out by making a small incision in the eye. In the older type of cataract surgery, the lens is taken out in one piece. Though, this surgery is rarely used today, but may be required in cases of trauma or dislocation of lens.

The lens which is put in the place of old cloudy lens is called intraocular lens. This lens comes with an optical power selected by the surgeon to give normal vision. This lens does not require any special care. The function of this lens is to focus light onto the retina and improve the vision. Cataract surgery does not require a patient to stay in the hospital and can be done in one hour.  Patient is under some kind of sedative and numb drops are given to the eyes before the start of the surgery. If both eye need cataract surgery, the only one eye is treat at the time and next eye is treated after 4 – 8 weeks. The result of one eye will determine the next surgery in other eye.

The use of laser is bit expenses Cataract surgery in Delhi compare to other methods of the cataract surgery. The laser use improves accuracy but has no major impact on the result of the cataract surgery. It also does not reduce the recovery time.

Cataract surgery is considered very safe and the rate of success is more than 98 %. After the surgery, there may be some irritation in the eye and doctor may prescribe some medicine as pain reliever.  Some sensitivity to light Lasik laser in Delhi  and tearing in the eye may also occur, but all these are short term issues, which will go after few days. Doctors also recommend wearing dark glasses for few days. After the surgery, patient may need new prescription of eye glass. The use of reading glass after cataract surgery is needed. The consultation with eye surgeon must decide the type of treatment and other precaution during and after the cataract surgery.
