삼성안과처음으로 가기

최근 굴절수술학회지에 중간정도의 근시를 가진 사람에게

한쪽눈에는 마이토마이신을 이용한 표면절삭술(PRK)를 시행하고

다른눈에는 라식을 시행하여 결과를 비교한 논문이 발표되었다. 6개월 이상 관찰한 데이터에서

안경을 쓰지 않은 나안시력뿐 아니라 시력의 질의 척도인 수차,대비감도도 M-PRK군에서 우수하게 나왔다.

이는 M-LASEK, PRK등의 표면절삭술이 라식에 비해 안정성, 시력의 질면에서 우수함을

객관적 자료로 다시한번 학인해준 것으로 본원의 방침과도 일치한다고 할수 있겠다.

라섹의 불편함인 각막미세혼탁과 통증을 해결한 MP3 라섹이야말로

현재에서는 최선의 수술방법이 아닐까 생각한다.

Photorefractive Keratectomy With Mitomycin C Versus LASIK in Custom Surgeries for Myopia

: A Bilateral Prospective Randomized Clinical Trial

                                                          Anelise Dutra Wallau, MD; Mauro Campos, MD

PURPOSE

To compare photorefractive keratectomy (PRK) with prophylactic use of mitomycin C (MMC) and LASIK in custom surgeries for myopic astigmatism.

METHODS

Eighty-eight eyes of 44 patients with a minimum estimated ablation depth of 50 µm were randomized to receive PRK with MMC 0.002% for 1 minute in one eye and LASIK in the fellow eye. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), cycloplegic refraction, slit-lamp microscopy, contrast sensitivity, specular microscopy, aberrometry, and a subjective questionnaire were evaluated. Forty-two patients completed 6-month follow-up.

RESULTS

Mean spherical equivalent refraction error before surgery and mean ablation depth were –3.99±1.20 diopters (D) and 73.0±914.55 µm in LASIK eyes, and –3.85±1.12 D and 70.7±14.07 µm in PRK with MMC eyes, respectively. Uncorrected visual acuity was significantly better in PRK with MMC eyes 3 months (P=.04) and 6 months (P=.01) after surgery. Best spectacle-corrected visual acuity and spherical equivalent refraction did not differ significantly in the groups during follow-up (P>.05). Significant haze was not observed in any PRK with MMC eye. Mean higher order aberration was lower in PRK with MMC eyes postoperatively compared with LASIK eyes (P=.01). Better contrast sensitivity was observed in PRK with MMC eyes than LASIK eyes (P<.05). The endothelial cell count did not differ significantly between groups (P=.65). In terms of visual satisfaction, PRK with MMC eyes were better rated.

CONCLUSIONS

Photorefractive keratectomy with MMC appears to be more effective than LASIK in custom surgery for moderate myopia. During 6-month follow-up, no toxic effects of MMC were evident. Long-term follow-up is necessary to attest its safety. [J Refract Surg. 2008;24:326-336.]
