How Eye surgery works?
An eye surgery is one of the most intricate and delicate surgical procedures. It might be performed to treat an eye disease and to correct or improve vision in the affected eye. These types of surgeries require the expertise of an experienced eye surgeon or an ophthalmologist as the eye is one of the most delicate and sensitive vital organ of the body.
Eye surgeries employ various techniques and approaches depending on the disorder or the location of the deformity in the eye region.
An eye surgery may be performed using conventional open-type surgery or a minimally invasive surgery technique as well. Nowadays the use of laser technology in eye surgery is gaining quite a popular demand.
Eye surgery procedures
There are a number of different eye surgical procedures and the methods of performing these surgeries are also varied.
These are a few commonly performed eye surgeries along with their procedure techniques:
Laser Eye surgery
Laser eye surgical techniques use a fine beam of high-frequency laser light to perform delicate surgeries in the eye. Lasers can be used to treat refractive and non-refractive eye conditions. A corneal laser surgery uses a beam of laser to re-contour the surface of the eye. This procedure is used to treat short-sightedness (myopia), far-sightedness (hypermetropia) as well as distortion in the eye’s curvature (astigmatism).
This is the preferred option for surgery technique in case the patient wishes to avoid using eyeglasses to improve the vision in the eyes.
A cataract causes the crystalline eye lens to get cloudy or opaque. Cataract is often caused by aging, trauma or an eye disease and prevents the light from outside in making a clear image at the back of the eyeball on the retina. In case the condition gets severe as to result in loss of vision in the affected eye it might be required to surgically remove the optical lens and replace it with an artificial intra-ocular lens (IOL).
Due to the high number of cataract cases this type of surgery is one of the most common eye surgeries in the world.
Glaucoma consists of a number of diseases that affect the optic nerve in the eye, resulting in loss of vision caused due to a raised intra-ocular pressure (IOP). There are a number of different glaucoma surgeries that are either performed singularly, or in combination with others to allow the excessive aqueous humor (eye fluid) to drain from the accumulated area and lower the pressure on the optic nerve.
This is a minimally invasive surgical procedure used to drain the excessive aqueous humor from the eye’s natural drainage system in order to relieve the intra-ocular pressure (IOP) from the optic nerve. This surgery is performed using a micro-catheter which is inserted into the canal of the eye through a very tiny incision. The micro-catheter helps enlarge the main drainage channel and the connecting smaller channels by injecting a sterile and gel-like substance known as a ‘visco-elastic’. This surgery helps in reducing pressure from the optic nerve by draining excess fluid from around the optic nerve through enlarging the natural drainage system of the eye.
This is a group of eye surgeries that aim to correct deformities of the refraction of the eye by reducing or preventing the need for artificial lenses.
These are a few refractive surgeries:
- Keratomilleusis – This surgery reshapes the surface of the cornea to improve its refractive (optical) power. It requires the surgeon to remove a disc from the cornea, freeze it so that it can be quickly reshaped to remove unevenness from its surface then reattached to the cornea again.
- Laser assisted in situ keratomileusis (LASIK) – This surgery uses a high-frequency laser beam to correct the abnormalities on the surface of the lens in order to help improve vision in the eye.
- PRK (photo-refractive keratectomy
- LTK (laser thermal keratoplasty)
- CK (conductive keratoplasty) – This type of refractive eye surgery uses radio (sound) waves to reduce the corneal collagen in order to treat mild hyperopia.
- LRI (limbal relaxing incisions)
- RK (radial keratotomy)
- ICL (implanted contact lens)
A corneal surgery is used to correct abnormalities and disorders of the cornea through various different techniques and methods.
A corneal surgery includes most of the refractive surgical procedures as well as a few others, such as:
- Corneal transplant surgery – This surgery is used to remove a diseased cornea and replace it with a healthy donor cornea to improve vision.
- PK (penetrating keratoplasty)
- KPro (kerato-prosthesis)
- Corneal tattooing
- PTK (phototherapeutic keratectomy)
These types of surgery are used to mainly treat disorders affecting the retina in the eye.
These are some common vitreo-retinal surgeries:
- Vitrectomy – This surgery is performed using two different approaches. The ‘anterior vitrectomy’ is used to remove the front part of the vitreous tissue which is useful for preventing vitreous loss during a corneal or cataract surgery. It is also useful in removing displaced vitreous caused as a result of aphakia pupillary block glaucoma. Meanwhile, the PPV (pars plana vitrectomy) or TPPV (trans pars plana vitrectomy) is used to remove vitreous opacity and cloudy membrane with the help of a pars plana incision.
- PRP (pars retinal photocoagulation) – This is a type of photocoagulation technique to treat diabetic retinopathy.
- Retinal Detachment Repair – This surgery may use various methods such as: ‘ignipuncture’ which involves cauterizing the retina with a hot pointy instrument. ‘Scleral buckle’ is used to bend the sclera inward to repair the detached retina. This is done by either using a piece of preserved (donor) sclera or silicone rubber implant to sew the detached retina in place. A ‘laser photocoagulation’ can also be used to seal a tear in the retina.
- Macular Hole Repair
- Posterior Sclerotomy – This surgery is often used to remove a foreign body or to reattach the retina using an incision in the vitreous membrane through the sclera.
- Radial Optic Neurotomy
Eye Muscle Surgery
This surgery is used to correct the condition where a person’s both eyes are unable to align normally to focus on a fixed point. It is also known as ‘heterotropia’.
There are specific procedures for treating different muscle groups, such as:
- Loosening/weakening procedures – This involves recessing a muscle towards its origin by moving it in the posterior direction.
- Tightening/strengthening procedures – This involves moving the eye muscle towards the front of its original position as in an ‘advancement’ method or as an ‘adjustable suture’ surgery where an extra-ocular muscle is reattached by using a stitch that can be adjusted in length to tighten or loosen the muscle. This helps the surgeon to maintain a better alignment for the eye ball after the surgery.
This is a plastic procedure used to reform the eye and its related structure. These involve surgical treatments for droop eyelids, repairing tear duct obstructions and orbital fractures as well as removal of eye tumors. The oculoplastics procedures also involve surgical treatments such as laser skin resurfacing, brow lifts, eye lifts and face lifts.
Who is a candidate for Eye surgery?
You are considered a candidate for any type of eye surgery if:
- You suffer a traumatic injury to, or around the eye area
- You wish to avoid wearing eyeglasses or contact lenses, meant to correct your vision
- You suffer from a diagnosed eye disorder or eye disease
- The ophthalmologist suggests you to undergo an eye surgery to prevent or treat an eye disorder

As with any major type of surgery there might be a risk of certain complications arising in rare cases. These risks may develop as a result of an anomaly in the eye structure or due to an underlying condition.
These are certain risks seen after a laser eye surgery:
- Temporary disturbance of vision
- Discomfort in focusing
- Flap complications
- Irregular astigmatism
- Dry eyes
- Considerable regression, over-correction or under-correction
- Eye infection
There are certain risk factors that may arise after a cataract-related eye surgery, such as:
