Epi Lasik eye surgery or Epi-Lasik, which is an acronym for Epipolis Laser In Situ Keratomileusis is a one kind of laser vision procedure performed in our los angeles lasik center. It has evolved from PRK and Los angeles Lasik. The name epi-LASIK is derived from the greek word ‘epipolis’ that means superficial and the word lasik. Epi-LASIK eye surgery is just like LASEK except that in it the epithelial flap is created with the help of an epikeratome and thus the epithelial cells are not damaged by chemical toxicity of alcohol. It was introduced by Ionnis Pallikaris in 2003. By this Epi-LASIK procedure a lasik surgeon can solve some problems which occur during LASIK and also LASEK. Although Epi-LASIK is very similiar with Lasik and PRK, it has some differences from LASIK in operative produres.
Epi LASIK eye surgery procedure:
Alcohol treatment:20% ethyl alcohol kept in position for 45 second.
Separation of the epithelial flap : After 45 seconds of Alcohol Treatment, this procedure is performed by the dge of the trephine marks.
Corneal stromal ablation : This procedure like as PRK.
Reposition of the epithelial flap : After ablation the surface this procedure is performed by washing, scrapping with normal saline.
Bandage with contact lens : Applied contact lens for 5 to 7 days.
After Epi LASIK surgery managemant :
–Topical steroid for healing corneal epithelium.
–Topical artificial tear eye drops for using frequently.
–Bandage with contact lenses.
Epi LASIK candidates:
–Patient who is not fit for LASIK.
–Must be at least 18 years of ages.
–Corrective refractive conditions stable for last1 years.
–Myopic upto -10 diopter.
–Hyperopic upto +4 diopter.
–Astigmatism +- 6 diopter.
Complications of Epi LASIK :
–Poor adhesion and anchoring or delayed epithelial healing.
–Dry eye syndrome.
–Lost flap post operatively.
–Under correction and over correction of the eye correction.
–Haze cornea, haloes and glare.
–Loss of central corneal sensitivity.
Advantages of Epi LASIK:
–Corneal ectasia is less likely as residual corneal bed thickness is more.
–Flap related complications are not high like as LASIK.
–Additional correction of myopia up to 3 D more than LASIK is possible.
–For thin cornea it is the best option.
–Easy to create flap cornea.
–Very good option for high myopia.
–Overcomes the limitations of lasik.
Disadvantages of Epi LASIK :
–Post operative pain is more than Lasik.
–Blurred vision more tham 7 to 10 days.
–Corneal haze similiar to PRK is definitely encountered on long-term follow up.
Result of Epi-LASIK :Excellent.
Complications rate : few.
Healing Period : Delayed.
Lasik versus(vs.) Epi LASIK :
It has some extra advantages also from PRK(photo refractive keratectomy), in the form of less pain and less haze.
