Purpose
To evaluate the effectivess of the Puresee IOL (Johnson & Johnson) in correcting presbyopia and any complications or side effects from using this lens.
Setting
All patients were treated at Kingsbridge private hospital Eye Unit in Belfast, UK.
Kingsbridge eye unit is a state of the art facility with dedicated refractive diagnostic and treatment optiions. It provides laser and lens based treatments for refractive patients.
Methods
- 21 consecutive eyes of 11 patients who received puresee IOL were analysed.
- All surgeriies were performed by the same surgeon (first author) who is qualified in refractive surgery.
- Patients had a full refractive assesment including monovision tolerance.
- Patients had a full discusion and consent regarding the available treatment options.
- All eyes operated had no other significant pathology and normal corrected vision.
- The dominant eye was targeted for emmetropia (1st minus) and the non dominat eye was targeted for -0.5 to -1.0
- Biometry was obtained using the IOL master 700 (TM). Standard K was used for the calculation.
- Post operative results were collected for refraction, vision in each eye, complications and any photopsia symptoms.
Results
- 10 patients had bilateral puresee IOL implant
- 1 had 1 eye for near vision only.
- There were no intra-operative or post opertive complications.
- All eyes targeted for distance achieved snellen 6/6 or better.
- 8 eyes (72.7%) targeted for near achieved N8 or better (range N5-N8)
- 3 eyes targeted for near achieved N10, but they all had a post op refraction of less than the minimum target of -0.5 (0 to -0.36 SEQ)
- From the 10 eyes targeted for distance, 5 also read N8, 1 read N6 and 1 read N5
- 2 patients reported some photopic symptoms at night but these were not deemed significant enough to impede their activities ncluding driving.
Conclusions
- The puresee IOL when implanted with slight monovision achieved excellent presbyopia correction when refractive targets are met.
- It was well tolerated by patients with no complaints regarding distance vision or significant dys/photopsia.
- In our cohort of patients; the achieved SEQ was often less than that targeted. This can be important when targeting reading vision. 3 of our patients achieved under the targeted SEQ and had slightly reduced reading vision. Intrestingly they were all myopes and so it maybe prudent to target a higher myopic target in this group.
- 70% of distance eys also achieved good reading vision with that eye. A larger study of this lens is required to help better refractive targeting and patient selection.
