A.T. Robertson Commentary Luke 18:41

"What wilt thou that I should do unto thee? And he said, Lord, that I may receive my sight." — Luke 18:41 (ASV)

What wilt thou that I should do unto thee? (Τ σο θελεις ποιησω; ). Same idiom in Mr 10:51; Matthew 20:32 which see, the use of θελω without ινα with aorist subjunctive (or future indicative). See same references also for ινα αναβλεψω "that I may see again" without verb before ινα. Three uses of αναβλεπω here (verses 41,42,43).
