21M just diagnosed

My left eye is diagnosed with keratoconus ( moderate to advanced stage ) and left eye can only 6/36 even with correction and in contrast my eye right is just suspect keratoconus with corrected vision of 6/6. I'll go undergo cxl soon . What is worrying me rn is will scleral lenses help my left eye to see normaly again ? Anyone from India can you recommend the best hospital for treatment .
