General Eye Related Questions
Eye looks very small, but it is important complex organ in the body. To prevent avoidable blindness it is necessary to get an eye examination at least once in a year .
No. Wearing glasses only aids to see the objects clearly.
Patients will be able to focus on near objects. It is because the eye ball may be larger, the cornea may steeper or any other reason. Patient need to wear minus lenses in front of the eyes to see the objects clearly. However if the eye ball is too large or cornea is too steep even near objects cannot be seen clearly.
Patients will be able to focus on distant objects. It is because the eye ball may be shorter, the cornea may flatter or any other reason. Patient need to wear plus lenses in front of the eyes to see the objects clearly. However if the eye ball is too short or cornea is too flat even distant objects cannot be seen clearly.
At the earliest as the individual may not be aware of unknown and unidentifiable eye problems by themselve.
Generally human eyes will not be able to focus close objects ( news paper …etc) when the age is nearing 40 years. For few individuals it may be earlier than 40 years and for few individuals it may be later than 40 years. They need reading glasses/progressive glasses/bifocal glasses . If the patient is already wearing glasses for farsightedness or shortsightedness still the reading number should be separately incorporated in to the existing glass number(Progressive or bifocals).
LASIK Laser Eye Surgery Related Questions
- There are various types of laser surgeries related to eyes.
- LASIK Laser Eye Surgery to become Spectacle independent.
- Laser Photo Coagulation used in Diabetic Retinopathy and ROP Babies to prevent further damage to retina, Retinal holes and Macular Oedema
- Laser Yag Capsulotomy used in post cataract surgery patients who develops PCO
- Endolaser in eye retinal surgery
- Laser Iridotomy is used in Eye Angle Closure Glaucoma
- Laser procedures in various other conditions
- Lasik is a laser eye surgery to make the patient spectacle independent.
- This surgery is done on black portion of eyeball ( Cornea ).
There should be minimum thickness of cornea to perform this surgery ( Various thickness levels to various eye sight powers) ( a patient with -10.00 may get good result if corneal thickness is very good and a patient with -3.00 D may not be eligible for this surgery if the cornea is too thin). Again depending on the thickness of cornea eye surgeon can perform various kinds of Lasik laser surgeries ( Bladeless LASIK Eye Surgery, Conventional LASIK Eye Surgery, Customized Lasik, Lasek ,Epi Lasik and PRK). Some patients may not be eligible for all these surgeries.
Yes. We have other options to make spectacle independent .(Eg ICL)
18 years is the minimum age limit for LASIK Laser Vision Correction Eye Surgery.
NO, once if there is no eligibility for LASIK there won’t be any more chances in future.
YES, there are other procedures (Eg: ICL)
In LASIK eye surgery the first step is to create a very thin flap over the black portion of eyeball. This flap can be created with a specialized micro keratome blade (Conventional LASIK) or using highly specialized Femtosecond Laser machine (Blade less / Blade free LASIK). With bladeless LASIK there is more safety and more accurate flaps can be created. Also in Bladeless LASIK, surgeon can customize the flaps exactly how it should be to achieve best desired visual outcome.
Actual surgery is less than 20 sec per eye. Approximately 10 min per eye will be for complete operation theater time.
For any procedure a through eye examination is must. If any other eye related disorders present ,they should be treated first (Eg: Barrage Laser for Retinal holes). And there will be specialized eye examination ( Corneal Topography) with which eye surgeon determines the best suitable LASIK Eye Surgery or disqualifies for LASIK eye surgery
Generally we have to dilate for retinal examination ( the effect of medication will be around 3-4 hours). We cannot do LASIK eye surgery when the pupils are dilated. But we can do if we give a gap of 4-5 hours after dilatation by the time pupils get constricted. If the patient makes an appointment early in the morning for LASIK screening then in the evening we can perform LASIK eye surgery.
Generally next day patient can attend regular works. In case of PRK at least 3-4 days home rest may be necessary. Main criteria is to avoid dust, water into the eyes for first few days and regular medication even f they are in the office.
There will be mild irritation, watering and slight blurriness may be there after LASIK eye surgery for first 24 hours which quite normal.
Seldom there will be flap related complications especially in conventional (micro keratome blade assisted) LASIK eye surgery if the corneas are too flat/ too steep or deep seated eye balls. With femtosecond laser assisted LASIK these problems are well addressed. Other complications are like De-centration of the treatment when patient moves his eyes during laser firing and not following surgeons commands.
If any complication during the procedure do not be panic. We can reschedule later.Surgeon will decide the exact time.
At least one week prior to eye examination and LASIK screening and LASIK surgery contact lenses should be discontinued.
Patients below 18 years, pregnant ladies, lactating mothers ( up to 6 months of post delivery) , patients with very thin cornea and other ocular diseases
Retina Related Questions
Diabetic retinopathy, age related macular degenerations, retinal holes, retinal detachments.
Ideally every person should get dilated retinal examination. If they have Diabetes, High Blood Pressure, age related macular degenerations, short sightedness or any systemic problems then they should get mandatory periodical retinal examinations (generally every 6-12months).
Shortsighted people and diabetics who do not have diabetic retinopathy should get it done once in a year. Diabetics who have diabetic retinopathy should consult retina specialist to know the next visit (Depends on the stage of Diabetic Retinopathy. Patients with age related macular degeneration should get it once in 6-12 months.
Initially vision may be fine. As the diabetic retinopathy progresses vision might drop, suddenly if there is bleeding within the eye or gradually if they have macular edema (Swelling in the center of the retina) or in advanced stage of diabetic retinopathy.
Yes, if there is advanced diabetic retinopathy patients may become permanently blind if timely treatment is not done.
Patients with advanced stage of diabetic retinopathy will need laser (PRP) which is generally done in 3 sittings per eye. Patients with macular edema will need intra vitreal injections ( single or multiple) rarely laser. Patients with bleeding with in the eye ( Vitreous Hemorrhage) will need intra vitreal injections ( single or multiple). Very advanced stage of diabetic retinopathy will need surgery.
They can have Retinal degenerations, Lattice degenerations with holes, retinal holes, retinal tears, retinal detachments or choroidal neovascular membrane(CNVM).
For retinal degenerations we need to observe. For lattice degenerations with holes, retinal holes or retinal tears we need to do barrage laser. For retinal detachment we need to do retinal surgery. For CNVM we need to give multiple intravitreal injections.
Depending on the stage of macular hole vitreoretinal surgeon will decide to operate or not.
Dry type of age AMD needs anti oxidants an d 6-12 monthly retinal examination. Wet type of AMD 9 CNVM) needs multiple intra vitreal injections if it is active.
Yes. Most common is ROP. New born who are pre mature or low birth weight babies can have ROP.
Advanced stages of ROP will need Laser or surgery.
Squint Eye Related Questions
Squint means the two eyes are not aligned. Each eye looks in two different directions.
There are many types of squinting. The eyes can be inward deviated, outward deviated, vertical deviated or cyclo deviated. The squinting may be same in all directions or different in different directions. Squint may be constant or intermittent.
No squinting is not purely cosmetic eye problem. There are functional eye problems with squinting. A person with squinting cannot analyze depths ( Stereoscopic Vision). They can never see a three dimensional images ( 3D Images).
Yes. Most of the squints can be corrected.
Orthoptic corrections, special glass prescriptions for some type of squints. Surgical alignment for some of the squint types.
At the earliest is the best for squint correction. Squint surgeon will decides appropriate treatment at appropriate time.
There may be lazy eye ( Amblyiopa), or other internal eye problems , occasionally dangerous eye problems may be present in squinting eyes.
In young children at the earliest to rule out other eye problems.
3 to 7 days (Depends up on the type surgical methods)
most of the times squint will be corrected in two eyes even the appearance of squint is in one eye.
It is minor skillful daycare eye surgery.
At the earliest. If the squinting is constant all the time there is possibility of loss of functional vision and also functional vision may not develop if we do not operate or treat at appropriate time. If the squinting is intermittent we can wait or follow the directions of squint surgeon
Will squint surgery improves vision. Do the patient need to wear the glasses even after the surgery?
No, squint surgery only make the two eyes in same direction. Patients with preexisting glasses ( Spectacles) should wear them even after the squint surgery.
