Abstract Details

Purpose:

To compare the incidence of Microstriae after Lasik surgery using Moria Microkeratome 90 µm flap, and with the flaps created with Femtosecond Laser with 90 µm and 100 µm thickness with 120° lamellar side cut.

Setting:

Private Group Practise, Universal Lasik Centre Mumbai using Moria One Use-Plus SBK microkeratome, IntraLase (Abbott Medical Optics), operated on Zeis Mel 80.

Methods:

Retrospective chart review of 24 eyes of the 1062 operated for Lasik have developed microstriae at day 1 of the surgery using the IntraLase (Abbott Medical Optics) with 90 µm and 100 µm flap with 120° Lamellar edge , and the Moria One Use-Plus SBK microkeratome- 90µm Head

Results:

Microstriae observed with under slit-lamp microscopy were considered for evaluation in the study. 30 eyes were detected to have Microstriae on Day 1 of evaluation of the 1062 eyes operated with various Flap Makers. no clinically significance visual reduction was detected in 29 eyes and 1 patient required flap ironing in the OR. 25 eyes with Microstriae of 800 (3.125%) in eyes operated with Mechanical Moria One Use-Plus SBK microkeratome- 90µm Head. 03 eyes of 150 eyes (2.66%) after FS Flap created by AMO IFS 150 with a 90 µm flap thickness with edge cut 120° and 01 eye (0.892%) of 112 eyes after FS Flap with a 100 µm flap with edge cut 120°.

Conclusions:

Available evidence indicates that femtosecond lasers are efficacious devices for creating LASIK flaps, with accompanying good visual results. The 100 flaps appear more stable with lesser known visual complications and flap Stability and reduced incidence of Microstiae. Especially with the 120 °edge lamellar cut, the stability of the flap is much superior. These lasers have improved the safety and predictability of the lamellar incision step However there was no significant difference in the incidence of Microstria detected with the different Flap making techniques. Long-term follow-up is needed to evaluate the technology fully.
