Eye Floaters What is Eye Floaters Symptoms and Treatment For Eye Floaters
For us to see the world around us lightenters the front of the eye in passes through the vitreous beforeit's focused on the retina the vitreous is the clear gel like fluidinside the eye the retina is the lightsensitive tissuelining the back of the eye frequently tiny clumps of cells forminside the jail like the Trias the shadows these cons cast on thereading are what we perceive as floaters make an appearance dots circles lines clouds or cobwebs in the field divisionfloaters are more common as we reach
middle age time in our life in the vitreous gel canstart to thicken and shrank forming clumps or strandssometimes the shrinking at the vitreous can create tiny tears in the retina as pulls away from the wall of the I ifthese tears bleed new floaters may appear with flashes thevitreous gel is rubbing or pulling up the retina moving it slightly from its normalposition lining the back of the eye
flashes are flashes a blight that appearin your vision intermittently and may be noticeable off and on forseveral weeks to months trauma to the eye can often causefloaters and flashes also migraine headaches can causesplashes floaters and flashes can also be caused by retinal detachment seriouscondition requiring immediate attention warning signs have aretinal detachment are flashing lights a sudden appearance at noon floatersshadows in the side or prefer if your vision

blew it may be drained from under thedetached retina allowing it to settle back into itsnormal position against the back of the eye or a gas bubble may be placed in the eyeto push the right now back in place with pneumatic retina pack see a gasbubble is injected into the vitreous pace inside the eye the bubble pushes the retinal tearclosed against the back wall the I with this procedure the patientmust maintain a certain head position
for several days after surgery the gas bubble willeventually disappear laser or cry or therapy is also added toseal the retinal tear back in place the track to me is a surgery where thevitreous gel that is pulling on the retina is removed from the I and replaced witha gas bubble overtime fluid naturally replaces thisgas bubble in select cases silicon oil is usedinstead of gas
Laser Eye Lasik Surgery PreOp Patient Engagement and Education
Your has recommended that you undergoLaserInSitu Keratomileusis or LASIK Laser surgery to correct a vision problem. Butwhat does that actually meané The human eye is constructed like a camera. with a clear lens in the front and lightsensitive tissue at the rear. This tissue makes up theretina which acts like photographic film. Patient EducationIn an eye that has perfect vision, light rays passing through the pupil are focused by thelens to fall precisely at the center of the retina. There are many common problems thatcan affect the eye and prevent light rays from focusing properly on the retina.
Three of these problems, myopia or nearsightedness;hyperopia or farsightedness; and astigmatism can often be corrected or reduced with theuse of LASIK laser surgery. Patient EducationMyopia, or nearsightedness, occurs when the shape of the eye is too long or the curveof the cornea is too extreme. In this case, light rays are focused on a point in frontof the retina instead of on the retina itself. Hyperopia, or farsightedness, occurs whenthe shape of the eye is too short. In this case, light rays are focused on a point behindthe retina. Astigmatism occurs when the cornea is unevenlycurved,
causing light rays to fall off center or notto focus properly at all. In either case, LASIK laser surgery can beused to flatten all or part of the cornea . allowing your to cause the focalpoint of light entering the eye to fall more closely to the center of the surface of theretina. LASIK laser surgery is a relatively simpleand nonintrusive procedure that is designed to reduce or eliminate the need for glassesor contact lenses. LASIK laser surgery generally does not have any effect on a patient's overallhealth and there are no risks in choosing not to have the surgery.
When the operative field is numb, the will usean automated microsurgical instrument called a microkeratome. This tiny instrument will carefully createa thin corneal flap which remains hinged to the eye. Underneath this flap the inner layer of thecornea, called the stroma, is exposed. Next, your will use a computer to controlpulses of cool laser light. These pulses will delicately remove microscopically thin layersof cells from the stroma By removing tissue in this manner, your will tailor the new shape of your cornea according
to the exact nature of your vision problem.The entire procedure usually takes about 5 minutes and is painless. The corneal flap is then closed and the surfaceis rinsed. Following surgery, you'll be given protectivecontact lenses to wear for a few days while the corneal flap heals.
