Just like any other procedure, Lasik can cause some complications especially if the patient is not too careful on the post-procedure management. It is important that you always heed your doctor’s advice especially on the proper care as well as the do’s and don’ts of the procedure. So for those of you who are planning to get a Lasik eye surgery in Singapore or have been experiencing some post-procedure complications then this article will help you out with that particularly on how you will be able to manage it.
Check out these common postoperative complications in a Lasik eye surgery and learn the ways on how you can manage them:
Flap Dislocation – This complication usually shows up within 24 hours after the operation unless the problem is traumatic. Patients will start experiencing an immediate decrease in their visual acuity and significant pain. This is mostly associated to mechanical trauma like inadvertent eye rubbing and in some cases, dryness with inadequate lubrication.
For this complication, it is recommended that lubrication, frequent eye blinking, and wearing of protective eyewear during the earlier postoperative stages. It is important that you consider any appreciable flap dislocation in your eye as an emergency. You must refloat the flap right away and reposition it after you have inspected and cleaned the lamellar interface. You need to also be extra careful when removing the epithelial tags at the flap edge. Once you have repositioned the lamellar flap, you can place a bandage contact lens on it.
You can also treat a late traumatic flap dislocation in the same manner except when the flap has been lacerated in the process. If it is possible then you should try attempting reapproximation. However, if the flap becomes severely damaged then amputate it at the hinges using surgical scissors and then put a bandage contact lens until the stromal surface reepitheliazes. Once the patient is able to achieve refractive stability then surface ablation can be performed with MMC for some residual refractive error.
Flap Striae – This is usually considered as an intraoperative complication but it can sometimes go unnoticed until after surgery. It can be easily avoided by carefully examining the flap right away during the procedure’s conclusion. By applying a few seconds of compressed oxygen to the corneal surface, it will help the flap seat better and reveal striae or commonly known as Bowman’s crinkles. The gutter symmetry can be evaluated by aspiring gutter fluid using a vitrectomy light pipe tangentially or with a weck cell.
Retroillumination through a biomicroscope is probably the best way to evaluate a striae. Peripheral macrostriae and sometimes central Bowman’s crinkles don’t usually result in symptoms. You can just monitor them in the process. If the patient is feeling symptomatic with the central macrostriae, re-float the flap right away then stretch it gently to help relieve the striae with weck cells. A clinicaly significant striae may need the help of an epithelial debridement before it can undergo stretching. So make sure to check it first before proceeding onwards.
