My Mother is experiencing blur vision from almost 2 weeks now , she's diabetic and need to look at the issue !

Ghosting and double vision after lasik

I had lasik eye surgery and my main problem is ghosting (double vision) in my right eye even in a good lightened environment but the ghosting disappears in bright sunlight or when using 2% pilocarpine eye drops , I have halos in both eyes too, but not as significant and harmful as the ghosting.


My K value of right eye is 48 and left eye is 46.2. Right eye CCT is 582 and left eye CCT is 576. 4 months ago the K values were 47.7 and 46.0 respectively. Dr. JS Tatiyal, Prof. AIIMS, Delhi, examined my report and declared me FIT for Femtosecond lasik. He said I have no progression of keratoconus though my corneas are borderline steep. Right eye -4.00 -2.75*170° Left eye -6.00 -2.5*170° Fundus and other pentacam readings are normal. After lasik corneal thickness will be Right eye 350 Right eye 390 Are these corneal thickness still safe or will it make corneal too thin? ( Ectasia)? I want to know is Femtosecond lasik uses microkeratocome (tool) for flap cutting or is it BLADELESS?. I am afraid of developing buttonhole flaps due to borderline steepness of my corneas. Chances of developing buttonhole flaps? Please help

Glaucoma, one eye blindness

A diabetic patient, age: 75, severe blindness in one eye, minor vision in another eye as well. Had a concussion a few days back due to clots in the brain. Perhaps the vision has diminished further after that.


I will undergo LASIK after 2 weeks from now. Doctor will perform LASIK on Alcon Femtosecond Laser LASIK ( Model : FS 200). I want to know that is this Laser best in the market or better than that is available?. What is excimer Laser then? What is the difference between EX 500 and FS 200?. Is this Alcon FS 200 Femtosecond LASIK BLADELESS? Doctor said as I have a cylindrical power of -2.75 D, I may not have the desired result ( 10% chances). Best Laser correction is achieved if only spherical power exists. What is the issue! My BCVA is 6/9, doctor said. Will I be able to see 6/9 immediately after surgery or will it take time to reach to that level ? I have asked too many questions, please answer in detail one by one. Detailed answers are requested. Thanks
