The refractive surgery concept

Based on Essay For All Tutors, refractive surgery is the surgical procedure done to correct the spectacle power of the eye’s refractive error. It is performed mainly on people relying highly on contact lenses and glasses. It can also be done on people having a stable glass power or refraction once they are beyond 18 and 21 years old.

Examples of refractive errors are presbyopia, astigmatism, far-sightedness, and nearsightedness. In this case, refractive surgery helps improve or correct vision. Multiple surgical options may be used in the process. However, all the surgeries aim at improving the focusing ability of the front part of the eye.

Types of refractive surgery

Laster-assisted in situ keratomileusis (LASIK)

LASIK eye surgery is effective in correcting eye problems. It is used as an option to contact lenses or glasses. In this case, the specialist uses a cutting laser to alter the shape of the clear dome-shaped tissue located at the front of the eye for vision improvement by offering the necessary refraction. Some of the possible complications associated with the surgery are;

  • Over-corrections
  • Under corrections
  • Double vision, halos, and glare
  • Vision changes or loss
  • Regression
  • Astigmatism

According to our cataract and refractive surgery homework doers, the health conditions that increase the risk of complications after undergoing surgery are;

  • Persistent dry eyes
  • A weakened immune system
  • Autoimmune disorders
  • Corneal inflammation

Conductive keratoplasty (CK)

It is a non-invasive procedure using radiofrequency energy to correct loy hyperopia and presbyopia using astigmatism. With more development of other effective surgical techniques for vision improvement, most surgeons rarely use conductive keratoplasty. Some of the complications related to the process include aseptic corneal necrosis. After the surgery, a patient will likely complain of light sensitivity and foreign body sensation. See our online cataract and refractive surgery homework help services for more details.

Laser thermal keratoplasty (LTK)

According to our professional tutors, Laser thermal keratoplasty helps treat farsightedness by reshaping the cornea using a holmium-YAG laser. After the procedure, a person will likely have improved vision without reliance on corrective lenses or glasses. Since it is a non-invasive procedure, tissues are not cut or removed. The process entails shrinkage of the collagen fibers while steepening the cornea using the laser beam in a predetermined way. Some of the side effects of the surgery entail;

  • Regression of correction requiring re-treatment
  • A worsened dry eye condition
  • Irregular astigmatism
  • Corneal infiltration
  • Visual acuity loss
  • Double vision

Automated lamellar keratoplasty (ALK)

This type of medical procedure is also known as keratomileusis in situ. It helps correct an abnormal curvature in the cornea that hinders the ability of the organ to focus light on the retina accurately, resulting in a blurred or unclear image. It helps in treating near and far-sightedness.

Astigmatic keratotomy (AK)

Essay For All Tutors regard astigmatic keratotomy as a corneal relaxing incision surgery for correcting astigmatism. It works by flattening the steeper corneal ends. Some of the people that may benefit from the surgical procedure include;

  • Those without eye problems that may impair the recovery process
  • People having good general health
  • Stable eyeglass prescription for a minimum of one year
  • Having mild to moderate astigmatism
  • People desiring to minimize their reliance on contact lenses and glasses

Radial keratotomy (RK)

This is a type of refractive surgery for correcting farsightedness and myopia. It entails making small but deep surgical incisions in the corneal that seek to flatten it. Based on our tutors, myopia promotes excess corneal curvature. However, using radial keratotomy helps minimize vision problems like astigmatism and nearsightedness. Some of the complications associated with the surgery encompass;

  • Ocular inflammation
  • Ocular infections
  • Weakened corneas
  • Irregular astigmatism
  • Rupture risk
  • Light sensitivity

Photorefractive keratectomy (PRK)

Photorefractive keratectomy is a common type of refractive surgery. It helps treat refractive errors in the eyes using a laser to reshape the cornea. Various people are exempted from getting the surgery even though they may be having refractive errors. Some of the people disqualified from getting the procedure are people having;

  • Corneal injuries
  • Scars in the eyes
  • Eye infections
  • Cataracts
  • Breastfeeding mothers
  • Pregnant
  • Advanced Glaucoma

Cataract surgery

Our cataract and refractive surgery assignment help tutors define cataract surgery as a quick and painless surgical procedure for removing the eyes’ cloudy lens resulting in vision problems. The process entails giving a patient a new intraocular lens for correcting farsightedness and nearsightedness.

If the cataracts are very severe, impairing a person’s ability to perform their daily duties, then cataract surgery becomes essential as it significantly improves their vision. The safety and effectiveness of the surgery motivate people with stubborn cataracts to opt for the surgery. The eye lens consists of proteins and water. When cataracts form, the protein component of the lens disintegrates, making the lens appear yellow and cloudy.

Age advancement is the most common cause of cataracts. Additional causes of cataracts are previous eye surgeries, injuries, or certain medications. Once the cataracts form, they prevent adequate light penetration through the eye lens. That is why a person will likely experience double vision, halos around bright lights, or blurry vision. To improve vision, the eye specialist extracts the cloudy lens and substitutes it with a clear artificial lens.

How to perform a cataract surgery

A patient who needs to undergo cataract surgery needs to prepare in various ways for the surgery. Before the surgery, the eye specialist will assess the eye health, investigate for any signs that may disqualify the need for the surgery, examine the eye for its correct focusing power, and also determine the factors that may affect the efficiency of the surgery. Some of the steps involved in the cataract surgery are;

  • Perform topical anesthesia

In this case, the ophthalmologist will numb the eye surface by administering eye drops on the eye surface. Patients can also receive medication that will help them relax during the surgical procedure.

  • Make a tiny incision in the cornea using a blade or a laser. The incision is small and never needs stitches for closure.
  • Break up and extract the cataract. The primary process involved in this step is phacoemulsification. The specialist can use ultrasound waves to break up the lens into small pieces to be sanctioned,
  • Insertion of a new lens. After removing the cloudy lens, the specialist introduced the new lens through the made incision.
  • The final step of the surgical procedure is protecting the eye using a special shield.

Cataract surgery takes a short time of between 10 to 15 minutes. The patient can be discharged the same day after receiving the surgery. After the surgery, the surgeon should have some 15-30 minutes to monitor the response and progress of the patient. Some of the possible side effects of the surgery include;

  • Watery eyes
  • Red or bloodshot eyes
  • Gritty feeling in the eyes

Potential risks of cataract surgery

Despite the efficiency of cataract surgery, there are various risks that the patient may get. The procedure is very safe. However, the chances of developing post-surgery risk increase because of having medical conditions or certain eye diseases. Some of the risks a person can experience are;

  • Infection
  • Retinal detachment
  • Posterior capsular opacification
  • Visual disturbances
  • Blurred vision
  • Vision loss
  • Ongoing eye pain
  • Eye swelling
  • Eye bleeding
  • Glaucoma
  • Inflammation drooping eyelid

After the surgery and discharge from the hospital, the patients should take various practices to support the healing or recovery process. For instance, some of the recommended strategies are;

  • Wearing an eye shield when sleeping or as directed by the doctor
  • Wear sunglasses when outside
  • Avoid rubbing the eyes
  • Avoid contact of the eye with soap, shampoo, or water
  • Using eye drops as recommended by the surgeon

However, certain alarming conditions may require urgent contact with the healthcare provider after the surgery. Such conditions include;

  • Experiencing eye flashes or floaters
  • Vision loss
  • Worsening vision
  • Mucous discharge around the eye
  • Eye redness
  • Eye pain

Types of lenses used during cataract surgery

  • Astigmatism correction
  • Multifocal
  • Accommodating-focus monofocal
  • Fixed focus monofocal
