Usual Laser Eye Operations Including Lasik And PRK
Three well-known eyesight correction surgeries include LASIK, IntraLase and Photorefractive Keratectomy or PRK surgery.
Lasik Eye Surgery- Lasik is actually a 2-step vision correction treatment which has been quite successful in the treatment of myopia, hyperopia and astigmatism. The Benefits. The surgery of lasik is completed under local anaesthesia (eye drops). The first task in lasik, making the flap, will take approximately 30 seconds per eye, whilst the 2nd step, reshaping the cornea, will take around 15 seconds. There's no pain. Many people enjoy improved eyesight, without glasses, about a few hours of surgery.
The Procedure- The corneal flap is designed with the microkeratome. The flap is then folded back so that the excimer laser can reshape your cornea. The speed and accuracy with the Allegretto (excimer) Laser enables tiny amounts of tissue (100 times thinner than a human hair) to be removed, reshaping the cornea. The flap is next cautiously repositioned exactly where it closes naturally with no stitches required. The whole treatment is carried out using anaesthetic eye drops and a mild oral sedative.
The IntraLase Laser is the initial step in IntraLase laser eye treatment and it is utilized to produce a flap without the usage of a blade.
The Advantages- A blade-free way of creating the corneal flap which has replaced the microkeratome (a mechanical device that uses a metal blade). Creation of the flap merely takes roughly 30 seconds for each eye. It's less dangerous, a lot more exact as well as delivers much better outcomes.
Photorefractive Keratectomy- Photorefractive Keratectomy (PRK) utilizes the excimer laser to change the form of the cornea. PRK is a eye laser treatment method of which doesn't include making a corneal flap. Nevertheless, it's going to take longer for the eye to recover and there is more uncomfortableness than with a LASIK procedure.
The drawback- Some patients will not be well suited for LASIK and require a different treatment method to correct their vision. A really slim or inappropriately shaped cornea can indicate patients are unsuitable for lasik surgery.
The PRK Procedure- The surface cells on the cornea are removed and the frontal surface of the cornea is reformed to fix the refractive error. A soft contact lens bandage is positioned on the cornea to aid the process of recovery. Regeneration of the corneal area usually takes 3 to 4 days. Much like LASIK, the procedure is carried out utilizing anaesthetic eye drops and a mild oral sedative.
Severe headache! Enough to seek medical treatment?
I have had a severe heachache since Halloween. I attributed it to stress and then to sinus pressure. I have taken Excedrin Migraine, Excedrin Back & Body, oral Percocet, Aleve and I have recieved a shot of Toradol. I am in excruciating pain and I am at a loss as to what to do. I have had the headache, dizziness, severe nausea and now muscle spasms in the upper back underneath the shoulder blade. I am not sleeping well, I am irritable and also my upper calves and Achilles Tendon is very tender and throbbing. Should I go to ER or do I wait this out? Any advice would be appreciated! 
I think you should seek treatment, whether at an ER, local doctor or clinic. You may just need some pain relief but if this has been chronic and constant you should probably see a specialist sooner rather than later. There is also the possibility of more serious causes of chronic headache that can be outruled with simple tests. Good luck.
