Cataract Surgery

Introduction

Cataract surgery is one of the highest-performing and most common procedures for regaining vision by surgically removing the “clouded” eye lens. Cataracts lead to a visual shunt and can reduce participation in activities of daily living such as reading or driving. Due to this operation, the ocular refractor is refractive by substituting the turbid glass lens with an artificial intraocular lens (IOL) that can provide unprecedented visual resolution and, as a result, a dramatic enhancement in life quality.

What is Cataract Surgery?

Surgeons perform cataract surgery, an ophthalmic medical procedure in which they extract the opacified natural lens of the eye and implant an artificial lens of glass. Usually conducted as an outpatient procedure, they achieve excellent results and a high success rate, and experts consider it to be a safe and very effective refractive surgery for ophthalmic practice.

Why is Cataract Surgery Needed?

Treatment surgery for cataracts is necessary when cataracts impair vision to the point that performing daily activities is a challenge. Reasons to undergo cataract surgery include:

• Restoration of Vision: Improves clarity and sharpness.
• Enhanced Quality of Life: Makes activities like reading, driving, and recognizing faces easier.
• Preventing Blindness: Untreated cataracts can lead to total vision loss.
• Treatment of Secondary Eye Conditions: Reduces the risk of complications like glaucoma.

Types of Cataract Surgery

1. Phacoemulsification:

• The most common technique.
• Sonoporation of the cataract to aspirating the cataract.

2. Extracapsular Cataract Extraction (ECCE): 

• It involves removing the clouded lens in one piece.
• Typically used for advanced cataracts.

3. Femtosecond Laser-Assisted Cataract Surgery (FLACS):

• Based on laser technology, accurate incisions and cataract removal.

4. Intracapsular Cataract Extraction (ICCE): 

• Removes the entire lens and capsule.
• Rarely used due to advances in other techniques.

Procedure Steps

1. Pre-Surgery Consultation:

• From the surgeon’s view, there is the inspection of the cataract and eye tests and a discussion of possible lenses.

2. Anesthesia:

• Local anesthesia or numbing eye drops are administered.

3. Lens Removal:

• A corneal microincision is made and a cataract is extracted by one of the surgical modalities.

4. Lens Implantation:

• An artificial intraocular lens (IOL) is inserted into the eyes, which is used as a replacement for the natural lens.

5. Closing the Incision: 

• In most cases, stitches are not necessary since the incisions close themselves.

6. Post-Surgery Care:

• Saline eye irrigation and protective factors are available to assist healing.

Benefits of Cataract Surgery

• Improved Vision: Restores clarity and reduces glare.
• Quick Recovery: Most patients resume normal activities within a few days.
• Long-Lasting Results: Artificial lenses do not cloud over time.
• Enhanced Quality of Life: Makes daily tasks and hobbies easier.
• Reduced Risk of Falls: Clear vision reduces the risk of accidents.

Cost of Cataract Surgery

• United States: $3,500 – $6,000 
• United Kingdom: $2,500 – $4,500 
• Thailand: $1,500 – $3,000 
• India: $800 – $2,000 

Best Hospitals in India for Treatment

India is well known as a center that offers affordable, quality cataract surgeries. Top hospitals include:

• Metro Hospital Faridabad is a state-of-the-art facility that is capable of high-tech cataract surgery, including laser-assisted cataract surgery.
• Max Healthcare (Delhi): state-of-the-art technology and accomplished ophthalmologists are available.
• Fortis Healthcare Delhi, is well known in the world for its high success rates in cataract surgeries.

Risks and Complications

While cataract surgery is generally safe, potential risks include:

1. Infection: Rare but can be treated with antibiotics.
2. Swelling: Temporary swelling of the cornea or retina may occur.
3. Glare or Halos: Some patients experience visual disturbances, which typically subside.
4. Secondary Cataracts: Tor this disease (posterior capsule opacification (PCO) can happen, but this can be controlled by laser and surgical means.
5. Detached Retina: Rare but requires immediate medical attention.

Recovery

Recovery from cataract surgery is relatively quick and straightforward:

• First Week: Vision recovers slowly, and you must wear protective headwear in darkness.
• 1 Month: Most patients achieve full recovery and clear vision.
• Long-Term: Serial follow-ups guarantee the most optimal endpoint and postoperative complication identification.
