Explaining a car on Instagram: "Resurfacing a cylinder head is the process of machining the head’s mating surface — the area that seals against the engine block — to restore perfect flatness and ensure a tight seal with the head gasket.

Anusha Ratnam on Instagram: "After procedure i was ok but felt discomfort, pain & watery eyes for 3-4hrs (which is normal ). Not yo worry , sos medicine would be provided from the doctor prior.

Woke up as nothing happened and felt perfectly alright without pain & discomfort next morning ❤️ @dr.advaith @envisionlasik #viral #viralvideos #viralreels #lasik #lasikeyesurgery"
