Discontinue Lenses Before Surgery

Discontinuing the use of contact lenses before surgery is important to ensure the safety and success of certain surgical procedures, particularly eye surgeries. This is because contact lenses can affect the shape and health of the cornea, the clear front surface of the eye, which can interfere with the surgical outcome. Here are some general guidelines for discontinuing contact lens use before different types of eye surgeries:


Cataract Surgery: Many eye surgeons recommend discontinuing soft contact lenses for at least a week before cataract surgery. Rigid gas permeable (RGP) lenses may require a longer discontinuation period, often several weeks, to allow the cornea to return to its natural shape.  marketwatchmedia

LASIK or PRK (Refractive Eye Surgery): Before undergoing LASIK or PRK surgery, patients are usually advised to stop wearing soft contact lenses for at least two weeks and rigid gas permeable lenses for several weeks. The exact duration may vary based on the individual and the surgeon's recommendations.

Corneal Transplant Surgery: For procedures like corneal transplantation, patients typically need to discontinue contact lens use for a more extended period, often several weeks to a few months before surgery, depending on the type of contact lenses they wear.

Other Eye Surgeries: The discontinuation period for other eye surgeries may vary, so it's crucial to follow your surgeon's specific instructions. They will assess your situation and provide guidance tailored to your needs.

The reason for discontinuing contact lens use before surgery is to allow the cornea to return to its natural shape and stability, which is necessary for accurate preoperative measurements and a successful surgical outcome. Failing to follow these recommendations can lead to inaccurate measurements and an increased risk of complications during or after surgery.

Always consult with your eye surgeon for precise instructions on when to discontinue your contact lens use before any eye surgery. They will provide you with the most accurate and personalized guidance based on your individual circumstances and the type of surgery you are undergoing.

Cataract Surgery

Cataract surgery is a common and highly effective medical procedure performed to treat cataracts, which are clouding of the natural lens in the eye. Cataracts can cause vision problems, including blurred vision, glare, and difficulty seeing in low light conditions. Cataract surgery aims to remove the clouded lens and replace it with an artificial intraocular lens (IOL) to restore clear vision. Here are the key aspects of cataract surgery:

Preoperative Evaluation: Before the surgery, you will undergo a comprehensive eye examination to assess the extent of your cataracts and determine the best treatment approach. Your eye surgeon will also discuss the different types of IOLs available and help you choose the one that best suits your visual needs

Anesthesia: Cataract surgery is typically performed on an outpatient basis, and you'll receive local anesthesia to numb the eye. In some cases, your surgeon may offer options for sedation to help you stay relaxed during the procedure.

Surgical Techniques: There are two primary surgical techniques for cataract removal:

a. Phacoemulsification: This is the most common method and involves using ultrasound energy to break up the clouded lens, which is then removed through a small incision. A clear IOL is inserted in its place.

b. Extracapsular Cataract Surgery: In this approach, a larger incision is made to remove the cataract as a single piece. This technique is less commonly used today.

Intraocular Lens (IOL) Implant: After the cataract is removed, the artificial IOL is implanted in the eye to replace the natural lens. IOLs can be monofocal (correcting vision at one distance), multifocal (correcting vision at multiple distances), or toric (correcting astigmatism).

Recovery: Most patients experience a relatively quick and comfortable recovery. You may be given eye drops to prevent infection and reduce inflammation. You will need to follow postoperative care instructions, including avoiding strenuous activities and refraining from rubbing your eyes.

Visual Recovery: Vision improvement is often noticed within a few days, although it may take a few weeks for your vision to stabilize. Some patients may still require glasses for specific tasks, like reading or driving.

Follow-Up Appointments: You will have follow-up appointments with your eye surgeon to monitor your healing progress and address any concerns.

Cataract surgery is considered one of the safest and most successful surgical procedures. It can significantly improve your vision and overall quality of life. If you suspect you have cataracts or have been advised to undergo cataract surgery, it's essential to consult with an ophthalmologist or an eye surgeon to discuss your specific situation and treatment options. They will help you determine the most suitable approach for your needs and answer any questions you may have about the procedure.

Corneal Transplant Surgery:

Corneal transplant surgery, also known as keratoplasty, is a surgical procedure that involves the replacement of a damaged or diseased cornea with a healthy donor cornea. The cornea is the clear, dome-shaped front surface of the eye, responsible for focusing light onto the retina. Corneal transplant surgery is typically performed to restore vision and alleviate problems caused by corneal diseases or injuries. Here are the key aspects of corneal transplant surgery:

Preoperative Evaluation: Before the surgery, your ophthalmologist will conduct a thorough eye examination to assess the extent of your corneal condition and determine the need for a transplant. They will also assess the suitability of your eye for the procedure.

Donor Cornea: The donor cornea is obtained from a deceased individual who has previously consented to eye donation. Eye banks carefully screen and preserve the donor corneas to ensure their safety and suitability for transplantation.

Surgical Techniques: There are different types of corneal transplant procedures, depending on which layers of the cornea are replaced:

a. Penetrating Keratoplasty (PKP): In this procedure, the entire cornea is replaced with a donor cornea. It is used for conditions affecting all layers of the cornea, such as advanced keratoconus or severe corneal scarring

b. Lamellar Keratoplasty: In this approach, only the affected layers of the cornea are replaced, leaving the healthy layers intact. It includes techniques like Descemet's stripping automated endothelial keratoplasty (DSAEK) and Descemet's membrane endothelial keratoplasty (DMEK). These techniques are used for diseases affecting the innermost layer of the cornea, such as Fuchs' dystrophy.

Anesthesia: The procedure is typically performed under local or general anesthesia, depending on the patient's needs and the surgeon's preference.

Donor Cornea Transplantation: The surgeon removes the damaged or diseased cornea and replaces it with the donor cornea. Sutures are used to secure the transplant in place

Postoperative Recovery: After surgery, you will need to use prescribed eye drops to prevent infection and manage inflammation. Vision recovery varies from patient to patient and may take several months to stabilize.

Follow-Up Appointments: Regular follow-up appointments with your eye surgeon are essential to monitor your progress and make any necessary adjustments to your treatment plan.

Corneal transplant surgery is highly successful in improving vision and addressing corneal issues. However, it is a complex procedure that may carry certain risks, such as graft rejection or infection. Your ophthalmologist will discuss these risks with you and provide guidance on postoperative care and follow-up.

If you have a corneal condition that may require transplant surgery, it's important to consult with an ophthalmologist or corneal specialist to discuss your specific situation, potential treatment options, and the suitability of corneal transplantation for your needs.
