E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Postoperative inflammation in patients with pseudoexfoliatio lentis undergoing cataract
surgery |
Infiammazione oculare dopo intervento di cataratta in soggetti affetti da
pseudoesfoliatio lentis |
|
E.1.1.1 | Medical condition in easily understood language |
Patients enrolled in the study have “fragile” eyes due to an idiopatic condition called
pseudoexfoliatio lentis and characterized by white deposits on the surface of the
crystalline lens. |
I soggetti hanno occhi particolarmente fragili a causa di una
condizione idiopatica che si manifesta con depositi biancastri sulla superficie del
cristallino che sembra come si stesse esfoliando. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of bromfenac ophthalmic solution 0.09% for reducing
postoperative inflammation in eyes with pseudoexfoliation syndrome (PEX) undergoing
cataract surgery and receiving standard postoperative eye drops (dexamethasone
0.1% plus tobramycin 0.3% ophthalmic solution). |
Questo studio intende provare che l’aggiunta di un FANS in
collirio (il bromfenac) alla terapia antibiotico-steroidea standard è in grado di migliorare
i risultati della chirurgia della cataratta, in particolare in occhi proni alle complicanze
intraoperatorie e postoperatorie come quelli con sindrome da pseudoesfoliazione. |
|
E.2.2 | Secondary objectives of the trial |
In particular, our study is intended to demonstrate:
1) a reduction in the anterior segment inflammation in PEX eyes treated with standard
regimen plus bromfenac when compared to the standard treatment only. Anterior
chamber inflammation will be measured with the Laser Flare Photometer.
2) a reduction in the posterior segment inflammation and incidence of macular edema
in PEX eyes treated with standard regimen plus bromfenac when compared to the
standard treatment only. Macular thickness will be measured with the OCT. |
In particolare, intende dimostrare che:
1) l’infiammazione postoperatoria nella camera anteriore dell’occhio con PEX operato di
cataratta è minore negli occhi trattati anche con bromfenac collirio rispetto a quelli
trattati solo con la terapia cortisonica standard. L’infiammazione verrà misurata con il
Laser Flare Photometer, un nuovo metodo per quantificare precisamente la reazione
flogistica nel segmento anteriore dell’occhio.
2) l’infiammazione postoperatoria nel segmento posteriore dell’occhio, e di
conseguenza l’incidenza di edema maculare cistoide, è minore negli occhi trattati anche
con bromfenac collirio rispetto a quelli trattati solo con la terapia cortisonica standard.
L’infarcimento della regione maculare verrà misurato con il Tomografo a coerenza
ottica ad alta definizione (Spectral Domain OCT), una nuova tecnica per visualizzare e
quantificare precisamente la presenza di edema maculare. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients with cataract:
- with nuclear sclerosis of the crystalline lens graded 1 or more according to the LOCS
II classification (Lens opacities classification system II; Chylack LT et al. 1989);
- with classics sign of pseudoesfoliatio lentis (PEX).
The diagnosis of PEX will be made by demonstrating the pathognomonic white deposits
in the lens, cornea, iris and anterior hyaloid face by slit lamp examination. |
Occhi con cataratta senile e segni classici di pseudoesfoliatio lentis (PEX) saranno
inclusi nello studio. Solo occhi con cataratta senile con opacità nucleare di grado 1 o
superiore verranno inclusi nello studio, in base alla classificazione LOCS II (Lens
opacities classification system II; Chylack LT et al. 1989). La diagnosi di PEX verra’
fatta mediante la dimostrazione della presenza dei depositi biancastri patognomonici
sul cristallino, la cornea, l’iride e la ialoide anteriore mediante esame alla lampada a
fessura. |
|
E.4 | Principal exclusion criteria |
Patients with history of ocular inflammation or trauma, previous intraocular surgery,
corneal haze, retinal vascular disease, diabetic retinopathy, variation of the foveal
profile at OCT (including macular edema and epiretinal membrane), moderate to
severe age related macular degeneration or age < 60 year will be excluded. Only one
eye per patient will be included in our study. |
Pazienti con storia di infiammazioni oculari o trauma, pregressa chirurgia intraoculare,
opacita’ corneali, malattie vascolari retiniche o retinopatia diabetica, edema maculare,
membrana epiretinica, degenerazione maculare senile di grado moderato o severo, eta’
inferiore ai 60 anni. Un solo occhio per paziente potrà essere incluso nello studio. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Reduction of 30% of anterior chamber inflammation evaluated by Laser Flare
Photometry (LFP) in the bromfenac arm when compared to the non-bromfenac arm at
postoperative day 3. LFP is a new, non invasive, objective method to measure ocular
inflammation. |
Riduzione dell’infiammazione in
camera anteriore dell’occhio del 30% nel gruppo trattato con bromfenac rispetto al
gruppo non trattato in corrispondenza della terza giornata postoperatoria. La
valutazione dell’infiammazione verrà effettuata con Laser Flare Photometry. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Third postoperative day |
Terza giornata postoperatoria |
|
E.5.2 | Secondary end point(s) |
1) Macular thickness: proportion of patients with central macular thickness greater
than 300 microns at week 4.
2) Best corrected visual acuity (BCVA): proportion of subjects with BCVA equal to
10/10 at week 1.
3) Ocular discomfort: proportion of patients who had no ocular pain at day 3, evaluated
by OCGA questionnaire (the Ocular Comfort Grading Assessment measures 7 ocular
symptoms: eye pain, tearing, itching, foreign body sensation, photophobia, eye
discharge, and haziness). |
1) Proporzione di pazienti con spessore maculare maggiore di 300 microns misurato
con OCT a 4 settimane
2) Proporzione di pazienti con acuità visiva (con correzione) inferiore a 10/10 ad una
settimana

mediante somministrazione del questionario OCGA (Ocular Comfort Grading
Assessment: rileva sintomi oculari quali dolore, bruciore, lacrimazione, sensazione di
corpo estraneo, fotofobia, secrezione, offuscamento). |
