Implantable Collamer Lens (ICL) Surgery in Delhi, India

• If the person is not suitable for LASIK surgery.
• ICL surgery allows people who choose not to wear glasses and contact lenses.
• Career reason.
• Lifestyle reason.

• Refraction & Vision Assessment.
• Anterior Chamber Depth Measurement (by Ultrasound A-scan).
• Corneal Thickness Measurement (Pachymetry).
• Intra-Ocular Pressure Measurement (IOP).
• Corneal Diameter Measurement.

• Sulcus Fixated: These lenses are positioned behind the iris and in front of the natural lens of the eye. Following the surgery, they are not visible to observers, distinguishing them from the other two types. Currently, sulcus-fixated lenses are considered the most favourable option.
• Iris Fixated: As the name implies, these lenses are affixed to the iris using two claws incorporated into their structure. Due to their non-foldable nature, a larger incision of approximately 5-6 mm is required for their implantation.
• Angle Fixated: Placed in the anterior chamber of the eye, these lenses reside closest to the cornea. Consequently, they carry a higher risk to the cornea compared to the other types.

The Phakic Intra-Ocular Lenses (PIOLs) or Implantable Collamer Lenses (ICLs) are meticulously crafted, high-precision microscopic optical devices that have undergone extensive research and development. As a result of their intricate design and advanced manufacturing processes, these lenses are considered to be quite expensive.

To ensure accurate measurements of the eye, sophisticated ultrasound equipment is utilised during the preoperative assessment. This enables the ophthalmologist to obtain precise measurements and determine the appropriate specifications for the lens.

During the surgical procedure, high-quality surgical microscopes and other specialised instruments are employed. These advanced tools provide the surgeon with enhanced visualisation and precision, facilitating the precise placement and fixation of the lens within the eye.

The combination of cutting-edge technology, intricate manufacturing processes, and the use of sophisticated equipment contributes to the overall cost of the procedure. However, it is important to recognise that these investments are necessary to ensure the safety, effectiveness, and long-term success of the Phakic IOL or ICL surgery.

• The surgeon will create a small incision, approximately 3 mm in size, at the limbus, which is the junction between the black and white parts of the eye.
• Through this meticulously crafted incision, the Phakic IOL or ICL is carefully implanted into the eye and secured in the correct position. Following the implantation, the eye is thoroughly rinsed with a combination of antibiotics and other specialised solutions to prevent the occurrence of any infections.
• The entire surgical process is typically completed within a short duration of 10-15 minutes. This efficient procedure not only ensures minimal discomfort for the patient but also enables a swift recovery.

On the day of the Phakic Intra-Ocular Lens (PIOL) or Implantable Collamer Lens (ICL) surgery, patients may experience mild discomfort and blurry vision. This temporary discomfort is a normal response to the surgical procedure and the presence of the newly implanted lens.

However, over the next few days following the surgery, the vision typically starts to improve gradually. As the eye adjusts to the presence of the lens and the healing process progresses, the patient's vision becomes clearer. This improvement in visual acuity is a positive indication that the surgery is successfully addressing the refractive errors and bringing the patient closer to their desired visual outcome.

The temporary discomfort and initial blurry vision experienced by the patient on the day of the surgery are expected aspects of the recovery process. The subsequent improvement in vision serves as a reassuring sign of the procedure's effectiveness and the patient's visual recovery.

Following the Phakic Intra-Ocular Lens (PIOL) or Implantable Collamer Lens (ICL) surgery, a follow-up examination is typically scheduled for the next day. During this initial follow-up, the ophthalmologist will assess the patient's eye condition, evaluate the healing progress, and ensure that there are no complications.

Subsequently, weekly follow-up examinations will be necessary for several weeks.

Before the surgery, patients should adhere to the following precautions and care:

1. Administer antibiotic eye drops for 2-5 days prior to the surgery.
2. Avoid using eye makeup during this pre-surgery period.

After the surgery, it is important to follow these guidelines:

1. Rest for 1-2 days immediately after the surgery.
2. Gradually resume light routine activities following the initial rest period.
3. Wait for one week before engaging in visually strenuous work.
4. Avoid vigorous physical activities for a month.
5. Refrain from splashing water into the eyes, swimming, and using eye makeup for a month.
6. Continue the medication as prescribed by the surgeon for approximately 2-4 weeks.
7. Adhere to the recommended follow-up schedule.

While ICL surgery is generally safe, there are potential complications to be aware of, including:

1. Glaucoma or an increase in eye pressure.
2. Damage to the corneal endothelium can lead to corneal oedema.
3. Damage to the natural lens of the eye, resulting in the development of lens opacities.
4. Introduction of infection into the eye, leading to endophthalmitis.

It's important to note that these complications are rare, and they can typically be managed effectively with appropriate treatment.
