Glympse for iPhone – Share Your Location with Friends

Glympse is an app that uses the iPhone’s internal GPS to transmit coordinate information to a website allowing others to track your position on a map. While this sounds like it could be a stalker’s dream app, the idea behind Glympse is that the user can send a “glympse” to an email address or as an SMS text message, inviting only those the user trusts to view their location – and then only for a set time period the user controls. Right now I’m using it to track my wife’s progress as she drives home from Portland in the rain. The app updates her position on the map every 10 seconds or so, giving me a glimpse of her location and speed (so I know she’s safe). Think of this as a peace-of-mind app, and its free no less (at least for now).

My PRK Experience: One Week Post-op Recovery

Its been a week and a few days since my PRK surgery, and my eye is healing quickly. I don’t have any near vision blurriness anymore and I’m guessing my distance vision is at least 20/20 since my left eye’s visual acuity is equal to my right eye with the corrective lens. In just 48-hours the initial post-operative farsightedness has resolved itself. In fact, because the vision in my left eye is so superior to my right, I recently became left-eye dominant at all distances. In the past few days, when I was experiencing post-op hyperopia, I had difficulty reading a computer screen with my left eye. Even at that near distance, the text on the screen was almost unreadable, so I resorted to covering my left eye in order to work without a headache. Now that I’m left-eye dominant, my right eye is seeing blurry text, while my left eye is sharp. In order to focus with my right eye, I have to cover my left and then concentrate on focusing with my right. Just crazy. My solution is simply to wear my old glasses with the left lens removed. This way, both eyes have the same prescription.

The optical aberrations seem to have abated as well. I don’t have ghosting issues anymore, in any lighting condition. I still see very faint halos and starbursts in my left eye, but they are significantly less intense than my right eye with corrected vision. My glasses, for some reason, create very large starbursts from bright light sources (e.g. headlights of oncoming traffic). Even without correction, my untreated right eye still produces more visible optical distortions than my left. Perhaps this is due to the wavefront technology of the Visx laser.

I’ll learn my exact visual acuity on Monday. Fortunately, my vision is fluctuating much much less throughout the day. I find that my left eye is at its worst in the evening. This may be due to the steroid drops, as I’ve read that eyesight tends to stabilize once the drops are discontinued. For now, I can’t wait until next Thursday when I have the right eye done. I don’t know how much longer I can stand such lopsided vision!

My PRK Experience: Day Six

Today marks a significant improvement in my recovery. I woke up this morning with my distance vision very sharp and my near vision improved, but still blurry. What a difference a few hours makes! I suppose most of the healing happens during sleep, emphasizing the need for uninterrupted rest during recovery. While my vision did fluctuate again today, the ups and downs were not as drastic, though my near vision degraded as the day wore on. When I put my glasses on (with one lens removed), I could see that my distance vision is not yet 20/20, but close (I’d guess 20/30 or 20/40).

I drove home from work in twilight and didn’t notice any night-time optical abberations that many post-op PRK patients complain about. I do still see halos around lights, but they are very faint and diffused, and not at all distracting. Strangely, my glasses were responsible for creating large starburts in my untreated right eye, clearly visible in the headlights of oncomming traffic during my drive home. I attribute this to the fact that my glasses are partially crazed from heat exposure.

I addressed two concerns to my surgeon in a quick phone call earlier today: possible over correction in my left eye and the fact that my pupils are different sizes. He alleviated both concerns, explaining that pupil size can vary as much as one millimeter in healthy people, and that variation is actually quote common. He also said my near vision should improve with time, and it is probably not due to over correction because it would be difficult to accidentally over correct an eye with such a low myopic prescription. Given the fact that I made such significant progress in the past 24 hours, I’m going to wait a bit before I become alarmed. They will also test my near vision at my next post-op appointment on Monday, so that should put to rest any questions about over correction. I was also asked to pour on the preservative-free lubricating drops, even though my eye doesn’t feel dry. Apparently the cornea can dry out easily after surgery and that can affect vision and slow healing. These drops are insanely expensive, but its my eye after all.

My PRK Experience: Day Five

My distance vision has been fluctuating all day with significant changes occurring every hour. It changes from slightly worse than my untreated eye to significantly better. My close vision has been consistently blurry though. I haven’t had any pain or symptoms of dry eye and I haven’t needed the lubricating drops today.

My PRK Experience: Day Four

My vision has fluctuated quite a bit today from blurry in the morning to less blurry in the afternoon. Now its back to “more” blurry but roughly equal to my uncorrected, un-lasered right eye. This greatly reduces the feeling of dizziness from the past few days. I didn’t experience any pain today either, so I’m definitely on the mend. I have noticed that my eye tends to worsen after an application of steroid eye-drops, but I can’t discontinue these drops since they slow the healing process and prevent scar tissue from forming.

Earlier today, at my post-op checkup, my surgeon removed the bandage contact lens after convincing himself that I had healed enough. He explained the epithelium had mostly regrown except for a small spot of opaque cells in the center. I should expect the healing trend to continue and these cells to smooth out and become more transparent in the next few weeks. At the appointment, my vision tested to 20/60, a definite improvement from the day before.

As for the optical aberrations, I don’t notice the star bursts or ghost-images anymore, although the halos persist. Rather than a solid ring of light, they appear as a soft, warm glow around light sources. I also notice that my distance vision is much crisper than my near vision, though both are blurry. This may be a sign that I had some mild presbyopia that was hidden by my nearsightedness, or it could mean that I was slightly over corrected by the laser. Hopefully this will also resolve during the healing process.

My PRK Experience: Day Three

My surgeon suggested that the worst day would be yesterday (day three) and he was right. I had very little pain today. In the morning I had some dryness that was quickly alleviated with some drops. I don’t feel the sand-in-eye pain at all now, its quite comfortable. Tomorrow I’ll be visiting the clinic again to have the bandage contact lens removed. Its possible that I’ll feel the scratchy pain again since the lens is providing protection for my eye as it heals.

While that was the good news, the bad news is my vision hasn’t improved at all. Its still incredibly blurry with a 9 o’clock ghost image and large halos around all lights (even during the day). I definitely cannot drive like this and I find it difficult to walk without feeling dizzy. I almost want to wear an eye patch and do the pirate thing for a few days since this just isn’t working. I’ve been told this is normal and I should expect blurry vision for another few weeks. Again, I’m glad I did one eye at a time!
