Abstract Details

Purpose:

Microincisional Glaucoma Surgery (MIGS) is becoming more popular due to its simplicity, rapid recovery, safety profile and acceptable IOP control. It is possible to do a power vectors analysis of the sphere-cylinder refraction to interpreted the refractive changes caused after the simultaneous operation of phacoemulsification plus trabecular drainage iStent in patients diagnosed with glaucoma and cataracts compared to phacoemulsification surgery. Our hypotheses is that trabecular iStent will not change the refraction index compare with Cataract surgery alone

Setting:

Hospital Universitario de Torrevieja, Alicante. Spain. Universidad de Alicante, Facultad de Optica y Optometria

Methods:

142 patients retrospectively treated at the Hospital of Torrevieja (Alicante, Spain) divide in 76 patients (Group 1) mean age ± SD, 74.27 ± 7.59 had Phaco + iStent; and 66 patients (Group 2) 74.23 ± 10.57 only Phaco. Refractive errors expressed by the vectors of power, M is considered the equivalent spherical, J0 (cross cylinder Jackson) with axes 0 ° and 180 °, and J45 (cross cylinder Jackson) with axes 45 ° and 135º . Blurring, the vector B was used. Intraocular pressure (IOP) was also controlled in both groups at one month.

Results:

Group 1 preoperative VA 0.46 ± 0.19, M - 0.73 ± 3.09, J0 -0.06 ± 0.54, J45 -0.12 ± 0.88, B 2.45 ± 2.26. Group 2 VA 0.43 ± 0.18. M -1.13 ± 3.07; J0 0.08 ± 1.18, J45 0.02 ± 0.96, B 2.48 ± 2.61. Postoperative group 1 VA 0.83 ± 0.18, M -0.39 ± 0.61, J0 0.09 ± 0.25, J45 -0.07 ± 0.29, B 0.71 ± 0.42. Group 2 VA = 0.86 ± 0.14. M -0.32 ± 0.91, J0 0.04 ± 0.37, J45 0.01 ± 0.29, B 0.79 ± 0.73. Initial IOP group 1 20mmHg, group 2 15mmHg; post-operative 14 mmHg both groups. Reduction Group 1 30% and Group 2 of 7%

Conclusions:

There are no statistical differences in postoperative blurring obtained in both groups, as in Visual acuity. Regarding on level of IOP both group got same post-operative IOP level but in group 1 there was an important reduction of the IOP from the initial level, group 2 did not have Glaucoma. iStent seems to be a safe device that will not affect the final refractive status or this is going to as the observe in cataract surgery alone
