목적: 본 연구는 누진다초점렌즈 구매자의 근거리 수평사위 종류를 파악하고 누진다초점렌즈 착용 전·후의 근거리 수평사위의 변화량을 조사하여 근거리 수평사위 종류에 따른 알맞은 누진다초점 렌즈 처방에 도움이 되고자 한다. 방법: 40세에서 80세 사이의 누진다초점렌즈 구매고객을 외사위 20명, 내사위 20명 두 그룹으로 나눴다. 두 그룹을 가입도에 따라 +0.75~+1.25 D는 Group 1, +1.50~+2.00 D는 Group 2, +2.25~+2.75 D는 Group 3으로 나눈 뒤 누진다초점렌즈 착용 시 근거리 수평사위의 변화에 대한 통계적 유의성을 검증하고자 하였다. 결과: 외사위 그룹의 가입도 처방 전 근거리 수평사위 평균값이 4.4±1.23 BI, 가입도 처방 후 근거리 수평사위 평균값이 6.7±1.26 BI이며, 그 차이값의 평균이 2.3±0.47 BI로 유의(p
Purpose: This research is to understand a type of near-horizontal phoria for Multifocal lenses customers and investigate a change of near-horizontal phoria after wearing Multifocal lenses. The results may suggest an appropriate prescription for Multifocal lenses by near-horizontal phoria type. Method: Forty Multifocal lenses customers, aged 40-year-old to 80 years, were divided into two groups and each group was made up of 20 exophoria and esophoria. The two groups were divided into three groups which addition is +0.75~+1.25 D for Group1, +1.50~+2.00 D for Group2 and +2.25~+2.75 D for Group3. It was investigated to verify the statistical relatives for change of near-horizontal phoria by wearing Multifocal lenses. Results: The Average of near-horizontal phoria in exophoria group before and after prescription for the Multifocal lenses was 4.4±1.23 BI and 6.7±1.26 BI respectively. Difference of the average was 2.3±0.47 BI and it was slightly increased(p< 0.05). On the other hand, each average of nearhorizontal phoria in esophoria group before and after prescription for the Multifocal lenses was 4.05±1.05 BO and 1.8±1.28 BO. Difference of the average was 2.25±0.55 BO and it was slightly decreased (p< 0.05). Conclusion: The results indicate that prescription of addition makes increase and decrease the near-horizontal phoria value of exophoria and esophoria respectively. It demonstrates that wearing Multifocal lenses for esophoria is more adaptable than exophoria.
