Gas bubble dissipated completely exactly 5 weeks after operation, however, vision is still blurry and mildly distorted, although it seems slightly better than pre-surgery. Doc did not explain to me, but thanks to medhelp, I now realise that recovery of vision, if ever, might takes months. Keeping my fingers crossed and praying a lot. Seeing doctor again next week, hope for some good news, but am prepared for the worst.
