Abstract Details

Purpose:

To restore the integrity and optical properties of the cornea acquired after ReLEx SMILE procedure however lost after laceration trauma.

Setting:

The S. Fyodorov "Eye Microsurgery" Federal State Institution, St. Petersburg Branch

Methods:

Patient C, 25years old. VApre-op OD0.03Sph-6.00Cyl-0.50ax110=1.00, OS0.03Sph-6.00=1.00. Refractive surgery was performed using the Smile technology. VA on the 1day post-op OD0.90, OS0.80. 3months after surgery, a patient, while playing with a dog received a scratch like trauma to the right eye. Complaints of a red eye, severe lacrimation, photophobia, deterioration in the quality of vision. Objective data:OD0.80Cyl-0.50ax15=1.20, OS1.20=1.20. Status localis: eyelids unchanged. Mixed injection of conjunctival vessels. Cornea–incision like rupture~3-4mm and flap displacement in the inner quadrant, local edema of the cornea.Deep-lying structures without pathological changes.Diagnosis:OD-traumatic rupture and displacement of the flap, operated moderate degree myopia using ReLExSMILE.

Results:

The wound was treated, the epithelium was removed from the bed of the cornea and the inner surface of the flap, reposition of the displaced corneal flap. 1 post-op day VA OD = 0.4. Status localis: Mixed injection of conjunctival vessels. Cornea - the corneal flap is adapted, local edema, epithelialization in progress, contact lens in the correct position. Deep-lying structures without pathological changes. In the postoperative period, in addition to the instillation of antibacterial and anti-inflammatory drugs (aminoglycosides, glucocorticosteroids 4 times a day for 5 days), the drug HYLOPARIN-COMOD® was used as a tear substitute, which was prescribed as instillations 4 times a day for 3 months. 1week post-op VA OD = 0.95 cyl -0.5D ax 0 = 1.0 Status localis: the cornea is transparent, the flap is adapted. Deepening structures without pathology. 1 month post-op Visus OD = 1.2. Status localis: the cornea is transparent, the flap is adapted. Deep-lying structures without pathology.

Conclusions:

This clinical example demonstrates the possibility of surgical intervention without switching to patchwork surgery: The flap remains a flap; The strength of its fixation is higher, due to the greater length of its attachment to the cornea; Festina lente – dynamic observation epithelial growth is necessary; Love animals on the safe distance :)
