Abstract
Purpose
To compare the refractive and visual outcome after implantation of Lentis MPlus
(Oculentis) multifocal intraocular lens (IOL) when applying LENSAR femtosecond laser
for capsulotomy and crystalline lens fragmentation versus performing these steps
manually by a single surgeon (who performs >800 cataract surgeries per annum).
Methods
In a retrospective analysis the outcome of 110 consecutive patients who underwent
IOL implantation after manual capsulorrhexis and standard phacoemulsification were
compared to the surgeon’s first (SAQ) 110 consecutive patients who underwent IOL
implantation using LENSAR for femtosecond laser assisted capsulotomy and crystalline
lens fragmentation. The multifocal Lentis Mplus MF30 or MF15 IOL was implanted in all
patients.<br />
Results
Patient demographics were similar between groups. Two patients planned to have
LENSAR femtosecond cataract surgery were converted to standard manual
capsularrhexis with phacoemulsification due to inability to dock the patient interface
on the ocular surface (one case of severe conjunctival chemosis following subtenons
local anaesthesia and one case with very narrow palpebral aperture). Pre-operative

spherical equivalent in the LENSAR group was 0.26 ± 4.17D (range, -11.8D to +9.25D)
and in the Non-LENSAR group was -0.22 ± 3.97D (range, -15.25D to +6.88D). Post-
operative spherical equivalent in the LENSAR group was -0.23 ± 0.45 D and in the Non-
LENSAR group was -0.07 ± 0.38 D(p>0.05). Unaided distance visual acuity post-
operatively was 0.10 ± 0.19 logMAR in the LENSAR group and 0.07 ± 0.17 logMAR in the
Non-LENSAR group (p>0.05). Post-operative best-corrected distance visual acuity was
0.01 ± 0.13 logMAR in the LENSAR group and 0.00 ± 0.14 logMAR in the Non-LENSAR
group (p>0.05). There were no recorded complications of surgery or post-operative
adverse events in either group.
Conclusions
The surgeon’s first cases of LENSAR femtosecond laser assisted refractive lensectomy
provide good results for post-operative refraction and distance visual acuity equivalent
to manual phako lensectomy in a high volume cataract surgeon. No additional risk of
complications was observed in the patients undergoing femtosecond assisted cataract
surgery compared to manual cataract surgery.
