![]() Require bandage contact lenses to cover the eyes until you recoverīecause PRK is considered elective surgery, it is unlikely insurance will cover it.Might create worse vision than before ( loss of best-corrected vision).Risk of under-correction or overcorrection.Corneal haze (cloudiness in the cornea).Glare and halos around lights, especially at night.Don't have underlying diseases, such as diabetes, that can affect healing.PRK is an excellent option for patients with thin corneas and those prone to dry eyes. LASIK also requires a thick cornea, while PRK does not. PRK is different from LASIK, which requires cutting into the cornea to make a foldable flap. Removing this layer exposes the cornea for treatment with an excimer laser. 2 This is the thin top layer of the cornea. Photorefractive keratectomy (PRK) is a vision correction surgery and a LASIK alternative.ĭuring PRK eye surgery, the corneal epithelium is removed. Luckily, there are alternatives to LASIK that can help you achieve perfect vision.īelow are the five best alternatives: 1. Other factors such as age, eye diseases, and general health might also disqualify you from LASIK. This procedure isn’t possible if you have thin corneas. The corneal flap is a piece of the cornea that is cut and briefly folded back to allow for laser treatment. LASIK surgery requires a thick cornea to create a corneal flap. ![]() For example, LASIK won't work if you have thin corneas. However, not everyone with vision problems is a good candidate for LASIK eye surgery. Today, 95% of LASIK beneficiaries report positive results many years down the line. Since its FDA approval in 1999, LASIK has undergone various developments to make it safer and increase its chances of success. LASIK eye surgery is one of several revolutionary treatments for visual problems. Thinking about LASIK? Start a conversation with an experienced Patient Counselor to find out if laser eye surgery is right for you. RLE is permanent and can correct farsightedness, nearsightedness, and astigmatism. Refractive lens exchange (RLE) is similar to cataract surgery, but is actually for those without cataracts. Or, they may also be placed between the cornea and iris. Phakic intraocular lenses (IOLs) are artificial lenses placed behind the iris and in front of the natural lens to correct vision. Intraocular lens implants (IOLs) are artificial lenses implanted to replace the natural lens. Small incision lenticule extraction (SMILE)is a highly specialized procedure that removes a disc-shaped piece of the cornea (lenticule) to reshape it. Laser epithelial keratomileusis (LASEK) is a minimally invasive procedure that involves making an epithelial flap instead of a thicker corneal flap. It's an excellent alternative for people with thin corneas. Note, that if you want to retain transparency of the background, you should always select the PNG format.Photorefractive keratectomy (PRK) is a minimally invasive and doesn’t involve making a corneal flap with an excimer laser. Now we can save it as a JPG or PNG image. Ok, we are done! And all in all we have spent just few minutes on removing the background from the picture. The feathering radius controls how many pixels it takes to transition from fully opaque foreground to fully transparent background.Ī small radius creates a sharp edge that is suitable for hard objects:Ī large radius gives an appearance of softness that works well for certain textiles and other soft or fuzzy objects: So, enter "-1" as the value of the Offset the Boundary option. To remove residues of the background we need to move the selection contour by 1 pixel inside. Negative values shift the contour inward: And that's the tool we need to make our cut out picture look truly perfect. Happily, PhotoScissors also has the Offset the Boundary option. Offset the EdgesĪs you can see, the contour has become much smoother now, but it still looks unnatural, because tiny fragments of the background are still visible. Low quality of the source file or complex backgrounds require some additional steps. However, sometimes you may want to additionally refine the image. Load the image you want to strip from its background into the program and PhotoScissors will automatically erase background from it.Įnjoy the fine result in just few seconds. So, the whole process looks as follows in PhotoScissors: Open the Image and Cut the Background With it, you can get impressive results with merely few mouse gestures. Yet, there is a simpler alternative – PhotoScissors. How to Remove Complex Backgrounds in Just Few StrokesĪsk anyone, and you'll probably hear that removing a non-trivial background from a photo is a tough affair.
