Interventions/Control_1

This study was conducted at the Hayashi Eye Hospital, Fukuoka, Japan, between April 4, 2021, and September 24, 2023, separately in 120 eyes with near ATR oblique astigmatism (near ATR category) and in 120 eyes with near WTR oblique astigmatism (near WTR category). The eyes were randomly assigned to 1 of 2 groups. One group comprised 60 eyes of 60 patients who were scheduled to undergo a 2.4-mm temporal clear corneal incision (temporal incision group).

Interventions/Control_2

The other group comprised 60 eyes of 60 patients who were scheduled to undergo a 2.4-mm superior corneal incision (superior incision group).
