삼성안과처음으로 가기

근시교정술에 대한 여러 궁금점과 불안해하는 생각들 중에 제일 큰것이 시간이 가면서 시력이 다시 떨어지지 않을까하는 것이죠

결론부터 이야기 하면 큰 걱정하지 않아도 된다는 것입니다.

물론 정확한 술전검사와 함께 검증된 수술기종으로 경험많은 수술자가 수술했을 경우라는 조건이 전제되어야 합니다.

 --------------------------------------------------------------------------------------

최근 근시교정수술(엑시머레이저)후 14년간 경과관찰 결과보고에 따르면 

-6디옵터 이하의 경도근시를 가졌던 군에서는 나안시력 0.9(교정시력 1.0), 근시도는 -0.17정도 였고

-6디옵터~-13디옵터의 고도근시  군에서는 나안시력 0.8(교정시력 1.0), 근시도는 -0.67정도였다.

수술후 각막미세혼탁은 3-6개월까지 있다가 1년후에는 사라지는 양상을 보였다. 각막확장증환자는 없었다.

3명에서 약간의 야간시력불편을 호소하였으며, 대부분의 환자에서 수술결과에 만족하였다.

위의 결과에서 보듯이 라섹(PRK가 발전된 수술)이 라식보다 장기적인 안전성이나 시력유지 효과가 더 뛰어남을 알수있습니다

여러분들은 빨리 회복되는 라식을 선택하시겠습니까? 혹은 초기 회복은 늦어도 장기적인 안전성이 뛰어난 라섹을 선택하시겠습니까?

토끼(라식)와 거북이(라섹) 중 누가 최종적으로 고지(안정된 시력결과)에 올라 승리할지는 스스로 잘 생각해보시기 바랍니다. 

A 14-year Follow-up of Photorefractive Keratectomy

Graziano Bricola, MD, PhD; Riccardo Scotto, OD; Maurizio Mete, MD; Simonetta Cerruti, MD and Carlo E. Traverso, MD

PURPOSE

To evaluate the long-term outcome of myopic photorefractive keratectomy (PRK).

METHODS

This prospective study included 31 patients (49 eyes) who underwent PRK between 1991 and 1993. A Summit UV200 excimer laser was used. Patients were divided into two groups—low myopia: preoperative <6.00 diopters (D) (range: –1.50 to –5.75 D) (n=19); and high myopia: preoperative ≥6.00 D (range: –6.00 to –13.00 D) (n=12). Long-term postoperative follow-up was every 2 years up to 14 years. Refraction, visual acuity, corneal status, and intraocular pressure (IOP) were evaluated. At 14 years, corneal topography and endothelial cell count were performed.

RESULTS

At last follow-up, manifest refraction spherical equivalent (MRSE) for the low myopia group was –0.17±0.8, uncorrected visual acuity (UCVA) logMAR was –0.06±0.55, and best spectacle-corrected visual acuity (BSCVA) logMAR was 0.00±1.00. The high myopia group had a final MRSE of –0.67±1.4, UCVA logMAR –0.11±0.55, and BSCVA logMAR –0.03±1.00. At 14 years, BSCVA for most eyes was at least equal to preoperative BSCVA. In both groups, haze increased between 3 and 6 months, then declined in the first year. A temporary increase of IOP was seen in 4 eyes. Complications were minor haze (2 eyes), transient anisocoria (9 eyes), and intraepithelial hemosiderin deposits (4 eyes). No abnormalities in endothelial cell count or morphology, astigmatism, or ectasia were noted. Three patients reported night vision disturbance, but the majority of patients were satisfied with the outcome based on subjective questionnaire (low myopia group: 84%; high myopia group: 75%).

CONCLUSIONS

Our study demonstrates the safety of myopic PRK. [J Refract Surg. 2009;25:545-552.]
