Cataract Surgery

Laser eye surgery, or commonly known as LASIK, is a refractive surgical procedure conducted on the eye using laser to correct vision problems such as astigmatism, presbyopia, hypermetropia and myopia (Wachler, 2016). Although the procedure is an efficient method to correct eyesight, there are many controversial topics surrounding the conduction of the surgery due to the many possible health issues and risks afterwards. While several clinics offer the opportunity to provide LASIK surgery, the consultation processes often omit the risks and side effects in detail which can encourage the desire to undergo surgery (Squire, 2010). One of the most common side effects include vision disturbances where the patient can experience halos and starbursts

The perception of depth is due to having two separate eyes creating two separate images, while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two aspects of the eye are not involved in laser eye surgery and will not be discussed in reference. The focusing of objects and images is very much part of laser eye surgery. In order for a clear visual image to be formed the image must come to a point on the retina. Light rays do not

Main Point One: In 2017, Wachler stated that LASIK eye surgery also known, as laser-assisted in situ keratomileusis is a procedure performed to correct nearsightedness, farsightedness and/or astigmatism.

because this data is not recorded. The timeline to complete the review of the cataract pre-op surgery process is November 30, 2015.

Dr. Mark Everett is the clinic coordinator and optometric physician of the Pacific Cataract and Laser Institute (PCLI) office in Spokane, Washington. A special surgical team, which includes seven surgeons, comes to the Spokane clinic to perform laser vision correction surgeries known as LASIK and other eye surgeries weekly. There are a total of 11 PCLI clinics throughout the northwestern United States that the surgical team cover. Competition from Lexington Laser Vision (LLV) in Vancouver, Canada, is charging lower rates and attracting potential customers away from PCLI. A local clinic, Eye Consultants, is heavily advertising in the local newspaper a price per eye that is significantly lower than PCLI. Dr. Everett clinic has the capacity to do more laser vision correction surgeries, and he wants to expand this service to keep current patients and attract new ones. An advertising campaign has already begun, but a clear strategic focus is needed to respond to this challenge.

The surgery is performed in a hospital. Before the surgery, you will be given a general anesthesia to ensure that you will not feel any pain. The surgery will take between 3 to 4 hours to complete. And you will need to remain in the hospital for several days.

The study has been conducted for the past twenty years. It found that among the 74,044 women who are 65 and older that all of them who had cataracts, 60 percent lower risk of death among the 41,735 women who did get them removed. Cataracts happen over time from age and most people end up having to get the surgery. The study show that because of the surgery it reduced people's risk of death from multiple health issues. Cataract surgery is probably the most successful surgery around because it is done so

Results: The study included 40 eyes of 21 patients. All patients completed at least 6 months

The treatment is a good replacement for other procedures such as laser resurfacing to treat fragile areas of the body such as around the eyes, the backs of the hands and the feet.

Within this essay I will write about elderly patients, undergoing cataract surgery, as a particular vulnerable client group. The local Health Board (2014) define cataracts as the clouding of the lens, occurring as a natural part of the ageing process, preventing light from adequately reaching the retina and therefore having an effect on vision. This can be corrected through the surgical process of Phacoemulsification, through which the clouded portions of the lens are removed and replaced with an artificial implant (Local Health Board, 2014). Whilst it is common for cataracts to develop as a result of old age, they can also occur as the result of injury, inflammation, degenerative disease, or from the prolonged use of medication. It is also possible for children to be born with cataracts.

The patient was brought to the operating room, and tetracaine was instilled in the operative eye. The patient was then docked with the LenSX Femtosecond laser. My preestablished protocol for the operative eye was administered with the laser, creating the primary incision, the side port incision, the capsulorrhexis, the nuclear grooves, and toric mark. The operative eye was then anesthetized with lidocaine given in a peribulbar fashion. The eye was then prepped and draped in usual sterile fashion. The previously created incisions were opened using a Slade spatula. The capsulorrhexis was inspected and found to be suitable. Gentle hydrodissection was then performed. Using the phacoemulsification handpiece and a Drysdale nucleus manipulator,

Laser surgery for glaucoma. Laser surgery for glaucoma slightly increases the outflow of the fluid from the eye in open-angle glaucoma or eliminates fluid blockage in angle-closure glaucoma.

Laser treatments can be considered an intermediate step between drug therapy and surgery for patients with glaucoma. Glaucoma is an eye disease which causes damage to the optic nerve fibers and consequently can lead to progressive vision loss or blindness if left untreated. The ciliary body in the human eye is constantly making aqueous humor providing sustenance to surrounding tissues and in order to maintain a healthy balance of this fluid it must leave the eye through the meshwork drainage system along the periphery of the iris. However, if too much aqueous humor is being produced or if the drainage system is not working properly, intraocular pressure builds, in turn causing optic nerve fibre damage and deterioration of vision. The main treatment for glaucoma is topical eye drops, but when a patient is on maximum eye

Eye color comes from the amount of melanin, a pigment found in the front part of the iris of the eye (Genetics, 2017). Lack of melanin results in blue eyes, some melanin gives green eyes, and a lot of melanin gives brown eyes. Cataracts are clouding of the lens that prevents light from entering. The cause of cataracts is unknown but there are possible reasons for it such as diabetes, smoking, and a lot of exposure to sunlight. Signs include lack of color intensity, night vision problems, fuzzy, blurry, or filmy vision. The function of the retina is to receive light the lens had focused on, switch the light into neural signals, and then send those signals to the brain for visual recognition. Most of the time eye floaters are from age related

Treatment of open-angle glaucoma usually begins with prescription eyedrops. These eyedrops lower pressure inside the eyeball, either by causing the eye to produce less fluid or by helping fluid to drain more. As an alternative to medication or when medication does not control glaucoma, laser surgery can be done. This surgery, also called laser trabeculoplasty, uses a laser to make the openings in the eye's drainage network larger. If medication and laser surgery are unsuccessful, conventional eye surgery may be necessary to make a new opening for fluid to leave the eye.
