Purpose.
To compare the refractive outcome of 2 different methods of intraocular lens implantation in cases of posterior microphthalmos, primary piggyback IOLs versus secondary iris claw lenses.
Methods.
This study was a retrospective interventional comparative study that included 60 eyes of 30 patients.
The included patients had bilateral microphthalmos with high axial hyperopia and had undergone a lens-based surgical procedure for hyperopia correction.
The included patients were equally divided into two groups.
The first group had undergone refractive lens exchange (RLE) with primary piggyback IOL implantation.
The second group undergone RLE with maximum available IOL power implanted followed by a secondary implantation of Artisan iris-fixated IOL (Ophtec B.V., Groningen, the Netherlands).
Results.
The 2 groups were highly comparable to each other regarding the mean age, axial length (AL), manifest refraction (MR), and K readings.
Postoperatively, there was a statistically significant difference between the 2 groups regarding the manifest refraction spherical equivalent (MRSE), mean absolute error (MAE), and uncorrected distance visual acuity (UDVA).
There was no significant difference between the 2 groups regarding the CDVA.
At 36 months, 20% and 73% of the eyes were within ±0.5 D of intended refraction at 36 months in 1ry piggyback and 2ry Artisan groups, respectively.
Fifty-three percent and 93% of the eyes were within ±1.0 D of intended refraction at 36 months in 1ry piggyback and 2ry Artisan groups, respectively (p=0.001).
Conclusion.
Secondary procedure with implantation of iris-fixated intraocular lens yielded very good results for treatment of axial hyperopia in cases of posterior microphthalmos.
The primary piggyback IOL showed less satisfactory results with cases of under correction and the possible complication of interlenticular opacification.
Both groups showed good safety parameters.
