Abstract: 
The objective of the present study was to compare single segment and double segment INTACS rings in the treatment of post-LASIK ectasia. In this interventional study, 26 eyes with post-LASIK ectasia were assessed. Ectasia was defined as progressive myopia regardless of astigmatism, along with topographic evidence of inferior steepening of the cornea after LASIK. We excluded those with a history of intraocular surgery, certain eye conditions and immune disorders, as well as monocular, pregnant and lactating patients. A total of 11 eyes had double ring and 15 eyes had single ring implantation. Visual and refractive outcomes were compared with preoperative values based on the number of implanted INTACS rings. Pre and postoperative spherical equivalent were -3.92 and -2.29 diopter (P=0.007). The spherical equivalent decreased by 1±3.2 diopter in the single-segment group and 2.56±1.58 diopter in the double-segment group (P=0.165). Mean preoperative astigmatism was 2.38±1.93 diopter which decreased to 2.14±1.1 diopter after surgery (P=0.508), 0.87±1.98 diopter decrease in the single-segment group and 0.67±1.2 diopter increase in the double-segment group (P=0.025). Nineteen patients (75%) gained one or two lines, and only three, who were all in the double-segment group, lost one or two lines of best corrected visual acuity. The spherical equivalent and vision significantly decreased in all patients. In these post-LASIK ectasia patients, the spherical equivalent was corrected better with two segments compared to single segment implantation; nonetheless, the level of astigmatism in the single-segment group was significantly better than that in the double-segment group.
