Will my eyes be as beautiful as it is now after vitrectomy or scleral buckle or any other surgery? Will there be any changes in the shape of the eye?

Not much change. Your eye most likely remain the same and beautiful. Vitrectomy will not change the shape or correction of your eye. You may have redness for a few weeks which will go away with drops and healing. Scleral buckle changes the eye's diameter to about 1 mm. But, it may not effect the external look of the eye. It will change the correction of the eye to become myopic.
