Eyehance - my experience

My name is Ivan, 48 yo, living in Brazil. Some 17 years ago I had a vitrectomy in my left eye due to severe opacities (floaters). Did the same in my right eye 4 years ago, when the condition on this other eye also became too bad.

My eyes are/were myopic, -2 in the left eye and -5 in the right eye.

Corrected vision has always been 20/20, due to anisometropia (3 diopters difference) I have always used contacts (instead of glasses).

In the last few years, vision in the first vitrectomized eye (LE) began to get worse. Had eye checks, but everything in order, and crystalline lens was clear (only some visible vacuoles/waterclefts). Tested 20/25 and increased prescription to -3.

In the last few months, I realized that this eye was developing a monocular triplopia. I saw three copies of everything. Any light point looked like a lambda, a mitsubishi or mercedes logo. This made it virtually impossible to read signs (stacked copies of the letters) and other basic tasks with this eye.

Went to a retina specialist, and had my eyes tested with an aberrhometer (hartmann/shack), that showed very strong high-order aberrations (mainly trefoil and spherical aberration). The refraction index of my crystalline lens was changing, but more in some regions (related to the "Y sutures", a natural symmetry of the lens fibers). This created 3 virtual lenses inside my lens, each one rendering one image in the retina.

After much research, including this forum, and discussion with the eye doctor, I chose an Eyhance for this eye. This is my dominant eye, and I did not want to afford losing contrast or good distance vision.

Had my surgery 5 days ago (was scared), everything went ok. Surgery was performed with LensX (femtosecond laser), supposedly allows for more precise cuts and centered position.

Day 0 - blurry vision, rings of light around everything, lots of glare, but underneath I could see that distant vision was very sharp.

Day 1 - less bluriness and rings. Went back to the doctor, checked ok, tested 20/15 uncorrected distance vision. I noticed that temporal peripheral vision was distorted (as if there was some residual jelly in the corner of my eye) and vision seemed to flicker when I moved my eye. From what I´ve read, supposedly the lens hasn´t yet been "wrapped"secure by capsule fibrosis, and still has some freedom to vibrate when the eyes performs the small, quick movements ("saccadic movements")

Right now, on day 5, the blurriness in the periphery seems to be less, and there seems to be less jitter when the eye moves as well. Distance vision is better than it has ever been in my life, this is what I imagine as perfect distance vision. Everything is very sharp until about 90cm. I can use a computer monitor at 80cm without glasses, but closer to this it starts becoming blurry. On Jaeger chart I can reach J10 (20/75). I can read my phone with standard fonts with my arms completely straight, certainly not confortable.

A low-add cheap reading glasses (+1.25) makes both monitor and cell phone very comfortable.

I am very happy with my distance vision, both day and night. No halos, glare, starbursts, nada. I was becoming afraid of driving, now I have the best vision in my life to hit the road. Even have to take care with the additional information that I perceive now (can read pretty much anything, recognize any face etc in my visual field).

I am hoping now that the jittering continues to decrease and subsides completely.
