there is new option in the market termed as Topographic Lasik. but different type of surgery is recommended based on your natural eye ,so go to an eye specialist who has , prk-lasik , lasik , smile & new topographic/contura vision Lasik. all these are lasers have different wave length and suitable for different type of eyes .the goal here is to smooth out the cornea in such a way that you get precise focus retina.
topographic scans the eye and computer identifies the physical topography of eye and creates a map of the cornea than multiple small laser are shot at it and smoothens down the cornea and the surgery is over the actual laser show doesn't last for i guess even 30 seconds ,and you are out in half and hour for both eyes ,due to prep and post surgery procedures.
Regarding your brother as someone pointed age factor that's true ,apart from that cornea thickness is quite critical secondly he is moving towards presbyopia age or that effect might have already began in a very miniscule stage so doctor wont risk the surgery. Good option for your brother LENS replacement using laser if he is hell bent of not wearing specs.
Regarding pain in topographic , you are sedated , but post surgery you are provided with eyedrops that you will have use as per the prescription .You will have keep our eyes more or less closed till ing (most surgeries are/must be done in morning by evening you will start recovery but you will be wearing dark glassed and continue the eye drops for next 15 -30 days. .And there would be immediate next day checkup by than almost you will have recovered your vision. and you will have some restriction of not touching the eye , no swimming avoid water near eyes .And wear sun glasses when you are outdoor or near dusty environment.
does it burn yes until evening ,bearable yes , depends upon ones ability to handle .have not faced issues yet .
If you are in the age group in 24-25 and wearing specs instead of buying silly iphones invest in this it would be specs free and a very active carefree life .If you are covered by your org with medical cover go for it . Medical cover doesn't cover low numbers , it covers higher numbers. i have given you the hint. ideal time is when your one year Mediclaim is going to expire do it in 11-10 month so automatically by next month you are again covered under Mediclaim.
If you are in Delhi than AIIMS Delhi has contura vision and the same procedure is done at fraction of cost ,of what private hospitals charge. i dont know which other aiims have similar options
