Can a topography scan or slit lamp or pentacam detect if someone has had custom topography guided surface ablation like Lesik surgery I'm curious how doctors can tell if this procedure was done before

Yes, corneal topography (including Pentacam) and slit lamp examinations can often, but not always, detect if someone has had custom topography-guided surface ablation (like LASIK or PRK). The specific features that indicate past surgery and the degree to which it's detectable depend on the type of procedure, the extent of tissue removal, and the individual's healing response.

I've been wearing glasses for 15 years with a power of 3.75 and I'm considering LASIK surgery to get rid of them. Is LASIK a good option for someone like me? What should I expect during the procedure and recovery? Are there any risks or side effects I should be aware of? Also, how do I know if I'm even eligible for it?

With a -3.75 prescription and 15 years of wearing glasses, you're likely a good candidate for LASIK. However, a consultation with an eye surgeon is crucial to determine if LASIK is the right option for you and to discuss any potential risks or alternatives.

I've been using preservative-free lubricant eye drops for about 10 months after my LASIK surgery and I'm wondering if long-term use is safe for my eyes. Are there any side effects I should be aware of with either preservative or preservative-free drops? I'm a bit concerned about potential harm from using them for so long.

It depends. Every LASIK patient experiences different levels of dryness and can use preservative-free eye drops after LASIK until the dryness abates. However, if you experience extreme and persistent dryness, do bring it to the attention of your doctor.
