What Happens During Keratoplasty Eye Surgery?
Keratoplasty eye surgery, performed under local anesthesia, usually takes less than an hour to complete. A cutting device is used to make a small incomplete flap across the cornea. While still attached at one side, the corneal flap is folded back to reveal the layer of tissue below. Another, very precise cut is made on the sub layer of tissue based on the person's glasses' prescription. After this cut, the corneal flap is placed back over the eye where it reattaches.
What Are the Advantages of Keratoplasty Eye Surgery?
Compared to other vision repair surgeries:
- The healing process for keratoplasty eye surgery is relatively quick
- It takes less time for stable vision to return
- Recovery period is more comfortable
What Are the Disadvantages of Keratoplasty Eye Surgery?
While keratoplasty eye surgery is a safe and effective surgery, it does have its disadvantages. They include:
- For people with mild to moderate nearsightedness, keratoplasty eye surgery is not as accurate as other eye procedures, meaning that its outcome is more difficult to predict.
- Keratoplasty eye surgery slightly increases a person's risk of developing an irregular astigmatism.
How Should I Prepare for Keratoplasty Eye Surgery?
Before your keratoplasty eye surgery you will have met with a coordinator who will discuss with you what you should expect during and after the surgery. During this session your medical history will be evaluated and your eyes will be tested. Likely tests will include measuring corneal thickness, refraction, and pupil dilation. Once you have gone through your evaluation, you will meet the surgeon, who will answer any further questions you may have. Afterwards, you can schedule an appointment for the keratoplasty eye surgery.
If you wear rigid gas permeable contact lenses, you should not wear them during the three weeks before keratoplasty eye surgery. Other types of contact lenses shouldn't be worn for at least three days prior to keratoplasty eye surgery. Be sure to bring your glasses to the surgery so your prescription can be reviewed.
On the day of your keratoplasty eye surgery, eat a light meal before going to the doctor and take all of your prescribed medications. Do not wear eye makeup or have any bulky accessories in your hair that will interfere with positioning your head under the laser. If you do not feel well that morning, call the doctor's office to determine whether the keratoplasty eye surgery needs to be postponed.
What Should I Expect After Keratoplasty Eye Surgery?
The healing time from keratoplasty eye surgery is very rapid. It usually takes only about 24 hours to mend. But it may take a few weeks for your vision to finally stabilize.
Your doctor will give you eye drops to control inflammation, discomfort, and prevent infection.

How Long Does a Retrobulbar Block Last?Retrobulbar block is an anesthetic procedure used for eye surgeries. Usually, lidocaine with epinephrine is injected into the retrobulbar space, which is the area located behind the eyeball (globe). It numbs the muscles around the eye by blocking cranial nerves II, III, and VI. This numbs the eye and also paralyzes the eye muscles temporarily so the eye does not move during the procedure.
Isopto Carpine (pilocarpine hydrochloride ophthalmic solution)Isopto Carpine (pilocarpine hydrochloride ophthalmic solution) is a cholinergic agonist prepared as a sterile topical ophthalmic solution. It is used to treat eye conditions such as glaucoma and other eye diseases, and is used during eye surgeries. Common side effects of Isopto Carpine include headache/browache, accommodative change, blurred vision, eye irritation, visual impairment (dim, dark, or “jumping” vision), and eye pain.
LASIK Eye SurgeryLASIK (laser in situ keratomileusis) eye surgery is a procedure in which a laser is used beneath the corneal flap to reshape the cornea. This process is used to treat refractive errors, improve vision, and eliminate or reduce the need for contact lenses or glasses. LASIK eye surgery comes in three main types: conventional LASIK, wavefront-optimized LASIK, and wavefront-guided LASIK.
Lotemax Ophthalmic Ointment (loteprednol etabonate)Lotemax Ophthalmic Ointment (loteprednol etabonate) is a corticosteroid indicated for the treatment of post-operative inflammation and pain following ocular (eye) surgery. Side effects of Lotemax Ophthalmic Ointment include minor burning when using the eye drops, feeling that something is in your eye, being more sensitive to light, headache, runny nose, sore throat, dry/red/itchy/watery eyes and elevated intraocular (inside the eye) pressure, which may be associated with optic nerve damage, cataract formation, and herpes simplex
MyopiaMyopia, or nearsightedness, makes it difficult to focus on objects that are far away. The condition runs in families and occurs because light focuses in front of the retina, instead of directly on it. Headaches, eye strain, and fatigue are symptoms of myopia. The condition is diagnosed by having an eye exam and can be treated by wearing glasses or contact lenses or by having refractive surgery.
Questions To Ask Before SurgerySurgery is the branch of medicine that employs operations in the treatment of disease or injury. Prior to surgery you might consider asking your surgeon questions about the operation (procedure).
What Is a Twitching Eye a Sign of?A blepharospasm (eye twitch) is a harmless tic of the eyelid muscle, which may resolve on its own. Conditions that may cause eye twitch include blepharitis, dry eyes, light sensitivity or conjunctivitis. Nerve disorders can also cause eye twitching.
What Is Dacryocystorhinostomy (DCR) surgery?Dacryocystorhinostomy (DCR) is a surgical procedure that involves restoration of the normal flow of tears through the tear ducts and alleviates the excessive tearing. Abnormal watering of eyes (epiphora) occurs because of an obstruction of the tear ducts, either due to structural problems or infection. This impairs normal tear drainage, which may lead to infection.
